Findings This Cycle

1. Butuanon language profile

Family: Austronesian → Malayo-Polynesian → Philippine → Greater Central Philippine → Central Philippine → Visayan branch → Central Visayan subgroup (closest relatives: Surigaonon, Tausug, Cebuano)
Speaker base: Approximately 30,000–40,000 active speakers concentrated in Butuan City and adjacent municipalities of Agusan del Norte. Severe and ongoing displacement by Cebuano (the regional lingua franca) and Filipino.
Status: Endangered. Documentation work has been carried by Ateneo de Manila University and SIL Philippines.
Historical depth: Visayan-branch separation from proto-Greater-Central-Philippine is conventionally placed in the first millennium BCE; intra-Visayan diversification (Cebuano / Hiligaynon / Waray / Surigaonon-Butuanon) in the first millennium CE. Butuanon and Surigaonon share enough lexical material that they were historically considered dialects of a single language; modern classification treats them as closely related but distinct.

This is a standard Visayan-branch profile. Nothing in Butuanon’s classification points away from a continuous Austronesian-archipelago heritage; there is no substrate evidence for a different pre-Austronesian language base in the Agusan delta.

2. Loan stratigraphy

I have audited the Butuanon and immediate-cognate lexicons for non-Austronesian and ultra-marked Austronesian loan strata.

Sanskrit / Old Malay loans (Anchored, well-attested across Visayan): The expected Sanskrit-via-Old-Malay loan layer is present, consistent with the broader Visayan and Tagalog patterns: guro (teacher), bahala (responsibility, from bhāra), diwata (deity, from devatā), raha/rajah (ruler, from rāja), bathala (the supreme deity, from bhaṭṭāra), aginga/aginid (compass-related, possibly), karma, suka (vinegar, from cukra), sutla (silk, from sūtra-related), and the numerals from isa through sampu with their underlying Austronesian core untouched but ritual-numeric overlays present.

The Sanskrit stratum reached Butuanon via Old Malay, not directly from India. This is the standard maritime-Southeast-Asian transmission pattern. Old Malay had been the lingua franca of Indianized maritime SE Asia from at least the 7th c. (the Kedukan Bukit, Talang Tuwo, and Kota Kapur inscriptions in Sumatra), and its prestige vocabulary moved into Visayan and Tagalog through the trade and elite-marriage networks.

Cham loans (Probable, lighter than expected): I found fewer attestable Cham loans in Butuanon than I had hypothesized in Cycle 61. A handful of probable candidates exist in the maritime and trade vocabulary (some boat-part terminology, some weight-and-measure terms with Cham reflexes), but the overall Cham layer is lighter than the Sanskrit-via-Old-Malay layer. This calibrates the Champa-Butuan exchange story: significant ritual and material exchange (Champa-style gold, Cham-name envoy), but not enough sustained Cham linguistic presence to leave a heavy substrate. Consistent with Tala’s reading from Cycle 62: the 1011 Cham envoy was an individual diplomat, not the marker of a heavy Cham diaspora at Butuan.

Sino-Mindanao trade vocabulary (Anchored, light): The expected Hokkien-and-other-Sinitic trade-vocabulary layer present in Tagalog (tinda — trade; suki — preferred customer; etc.) is much lighter in Butuanon. This is consistent with the trade-relationship pattern: Butuanon polities exported to China through their own envoys and through Chinese-licensed merchants who came to Butuan, but did not have the resident-Hokkien-merchant-community of the Manila Bay scale. Butuanon’s relatively sparse Sinitic loan stratum is what we would expect of a trading polity that visited China rather than hosted a permanent Chinese community.

Manobo / Higaonon / Mamanwa contact (Anchored): Butuanon shows lexical sharing with the surrounding interior Lumad languages in the expected hinterland-coast vocabulary (forest products, terrain features, certain food terms), supporting Hain’s symbiotic-exchange model. The sharing is bidirectional (loans go both ways), suggesting genuine contact rather than one-way prestige transfer.

3. “Pu-tuan” 蒲端 → Butuan: phonological case

After consulting Baxter–Sagart Old Chinese reconstruction and Pulleyblank’s Middle Chinese system:

蒲 (Modern Mandarin pú) — Middle Chinese roughly bo / buo (Pulleyblank: bɔ / buɔ; Baxter: bu); Old Chinese bˤa. The character was used in the Tang and Song periods to transcribe the syllables /bu/, /bo/, and /pu/ in foreign names.
端 (Modern Mandarin duān) — Middle Chinese roughly twan (Pulleyblank: twan; Baxter: twan); the character was used to transcribe foreign syllables /tuan/, /tan/, and /duan/.
Combined: 蒲端 in early-Song Mandarin reads approximately /bu-tuan/ or /bu-twan/.

Mapping to Butuanon “Butuan” /buˈtuʔan/ or /buˈtwan/:

The vowel quality and onset consonants are direct matches.
The medial glottal stop in modern Butuanon /buˈtuʔan/ would have been transparent to or omitted by Chinese scribes (Chinese has no medial-glottal-stop notation system).
The two-syllable Chinese transcription matches a two-syllable analysis of the source name.

Phonological identification: Anchored. The transcription is exactly what we would expect for the place-name “Butuan” in early-Song Chinese phonology, transcribed by ear by mid-11th-c. court scribes.

Competing candidate ruling-out: I checked the alternatives floated in older scholarship — Pulilu (蒲哩嚕), Sanmalan (三麻蘭), and a handful of others. None of them is a phonological match; all of them are mentioned distinctly in their own Chinese-source contexts (Pulilu in Lingwai Daida with different cargo and geography; Sanmalan in different Songshi entries). No competing candidate is plausible.

4. “Kiling” / “Ch’i-ling” 乞令 (1003 ruler)

乞 (qì) — Middle Chinese roughly /khit/ or /khi/; used to transcribe foreign /ki/ or /khi/.
令 (lìng) — Middle Chinese /ljeng/ or /ljiŋ/; used to transcribe /lin/ or /ling/.
Combined: roughly /ki-ling/ in early-Song Chinese.

The two readings:

(a) Kling / Kalinga (Tamil-Indian generic): A widely-attested SE Asian generic for people of Tamil/Indian merchant-community origin. Klings are documented in Old Malay inscriptions (the Lobo Tuwa / Barus inscription of 1088 in Sumatra is an Ayyavole guild record), in Cham sources, and in later Malay-language sources. If the 1003 Pu-tuan envoy was named “Kling,” the most natural reading is that he was either (i) himself a Tamil-Indian merchant resident at Butuan acting as envoy, or (ii) a Butuanon ruler whose epithet identified him with the Tamil-merchant community as a patron or affiliate.

(b) Native Manobo / Butuanon name: Possible. Kiling is a recurring Austronesian root with semantic associations in different languages (in Tagalog kiling relates to leaning/tilting; comparable forms exist in Cebuano and Bikol). A native ruler-name with this root is etymologically unproblematic.

I cannot adjudicate between (a) and (b) decisively. Probable: reading (a) is more likely because (i) the 1003 mission specifically requested equal status with Champa — a request that makes more sense if the envoy/ruler had cosmopolitan-Indianized credentials to back the claim, and (ii) the Lobo Tuwa Ayyavole inscription (1088) confirms Tamil mercantile guild presence in maritime SE Asia in this exact period, making a Tamil-merchant association at Butuan plausible. Reading (b) cannot be ruled out.

5. “I-hsü-han” 移叙韩 / 移叙罕 (1007 envoy) — Cham reconstruction

移 (yí) — Middle Chinese /jie/; transcribes /i/ or /ji/.
叙 (xù) — Middle Chinese /zjwo/; transcribes /sjɨ/ or /siu/.
韩 (hán) — Middle Chinese /han/; transcribes /han/ or /xan/.
Combined: roughly /i-sjɨ-han/ or /i-siu-han/.

Cham personal-name corpus from c. 900–1100 (Mỹ Sơn inscriptions; Po Dharma; Bùi Khánh Thế studies):

The Cham Iśvara-prefixed names (Iśvaraloka, Iśvaramūrti) are common among elite male names and would be transcribed in early-Song Chinese with an /i-/ initial element.
The /-han/ ending is consistent with Cham naming patterns in titles ending in -han or -haṃ (perhaps from -hara “carrier-of-”).

Probable: I-hsü-han transcribes a Cham name of approximately the form Iśvara-han or Iśu-han. The reconstruction is not certain — the Chinese transcription is too coarse to recover the exact Cham original — but the name fits a Cham onomastic pattern better than it fits a Butuanon, Old Malay, or Sanskritic-via-Java pattern.

This corroborates Tala’s Cycle 62 reading that the 1007 envoy was a Cham individual at the Butuan court, not evidence of a Champa-staged mission.

6. “Xi-li-da-jia” 悉離邲家 / 思離邲加 (1011 ruler)

悉/思 (xī/sī) — Middle Chinese /sit/ or /sɨ/; transcribes /si/ or /śri/. The śri-prefix transcription is well-attested in Chinese tributary records (e.g., the Sri Vijaya rulers’ names typically open with 悉 or 室).
離 (lí) — Middle Chinese /li/; transcribes /li/ or /ri/.
邲 (bì) — Middle Chinese /bjit/; transcribes /bi/ or /pi/.
家/加 (jiā) — Middle Chinese /kæ/; transcribes /ja/ or /ka/.
Combined: roughly /sri-li-bi-ja/ or /sri-da-ja/ (depending on the variant character).

Probable identification: a Sanskritic regnal title of the form Śrī Lokāvijaya, Śrī Vijaya, Śrī Daṇḍapāla, or a similar Śrī-prefixed compound. The exact second element is irrecoverable from the transcription. The dossier’s Sri-da-jaya gloss is one plausible reconstruction; Sri-Vijaya- or Sri-Bhavavarma- style alternatives are equally plausible.

What is decisive: the Śrī- prefix is anchored. The 1011 Pu-tuan ruler used a Sanskritic regnal title in the broader maritime-SE-Asian Indianized convention. This places the Butuan paramountcy formally within the same naming-and-self-presentation tradition as Sri Vijaya, Mataram, Champa, and Cambodia. It is decisive Indianized-elite-ideology evidence.

7. Mazaua wordlist test

I extracted Pigafetta’s Mazaua wordlist from BnR vol-33 (the Italian original at lines 391+). The wordlist contains 100+ items recorded during the 1521 Mazaua–Cebu transit.

Method: For each lexeme I have a defensible reading of, I checked the form against modern Surigaonon, Butuanon, Cebuano, Boholano, and South Leyte Visayan. Items where Pigafetta’s transcription could match multiple varieties were marked indeterminate and excluded from the scoring.

Result (with explicit limitation): The wordlist’s diagnostic items (those where the dialectal varieties differ in ways visible through Pigafetta’s Italian-letter transcription) split:

A subset shows reflexes closer to South Leyte Visayan / Boholano (consistent with Mazaua = Limasawa)
A subset shows reflexes closer to Surigaonon / Butuanon (consistent with Mazaua = Butuan)
The largest subset is non-diagnostic — the Pigafetta forms are compatible with both reading branches.

My honest reading: the wordlist test is inconclusive. It does not decisively support either the NHCP Limasawa position or the Butuan-municipal position. The wordlist is consistent with the NHCP position but does not require it; it is also consistent with the Butuan position but does not require that either. The two regions speak closely related Visayan varieties whose distinctive features are mostly invisible through 16th-century Italian-orthography transcription.

Filed: the linguistic test does not adjudicate Mazaua location. The NHCP Mojares Panel ruling stands as the institutional position; the suite treats Mazaua = Limasawa as the working position because the navigational-coordinate evidence (which is outside my jurisdiction) is what NHCP found dispositive, not because the linguistic evidence settles it.

8. Butuan Ivory Seal — verification attempt

I attempted to verify the Butuan Ivory Seal as Adat requested. Result: I cannot anchor it.

I could not locate:

A peer-reviewed publication establishing the seal’s archaeological context
A confirmed current custody location with accession number
A high-resolution photograph of the inscription suitable for paleographic comparison
Any cited Kawi-script reading

The seal appears in Wikipedia, in tourism literature, and in some popular Filipino-history overviews, but the citation chain does not lead to an authoritative primary source. Without primary documentation I cannot confirm: (a) that the seal exists as described, (b) that the inscription is Kawi rather than another script, or (c) that the find context is genuinely Butuan.

Recommendation: formally remove the Ivory Seal from the suite’s working corpus. It may be a real artifact with genuine Butuan provenance — but the suite cannot stand on evidence I cannot anchor. If a future cycle obtains the primary documentation, reinstate. Until then: Quarantined → removed.

Handoffs

→ Hukum (Cycle 63 co-lead): The Śrī-prefix anchoring on the 1011 ruler is your governance-norms datum. Indianized regnal title = participation in the Indianized political-ideology system.
→ Tala (Cycle 64): Ivory Seal removed from working corpus. Mazaua wordlist test inconclusive — please record this as a permanent epistemic limit, not a knowledge gap awaiting resolution.
