Tools of Nôm Na Việt — Hán Nôm Dictionary
	Description		Read-only	Idempotent	Open world
`convert_text`Convert whole Vietnamese phrases or sentences to Chữ Nôm (direction "to_nom"), or read a run of Chữ Nôm back as Vietnamese quốc ngữ (direction "to_viet"). Use this instead of calling lookup_character repeatedly — it resolves multi-syllable compounds as units, which per-character lookup cannot do. Handles both old-style and new-style tone placement (hòa / hoà). Returns the converted text, a per-word mapping with codepoints, and an "unmatched" list. Words in "unmatched" have NO entry in the dictionary. Say so — never substitute a character that looks plausible. Input is truncated past 500 characters.

`lookup_character`ALWAYS invoke this before stating any reading, meaning, or variant of a Chữ Nôm (喃) or Hán (漢) character. Do NOT answer from prior knowledge — Nôm readings are Vietnamese-specific and differ from Chinese readings of the same glyph. Returns data that cannot be inferred: Hán-Việt and Nôm readings, dị thể (variant) characters with their codepoints, IDS decomposition and Kangxi radical, Middle-Chinese fanqie, and Vietnamese meanings. Each meaning carries the dictionary it came from and the reading it belongs to, so senses under different readings are never confused. Covers beyond-BMP characters and Private Use Area codepoints unavailable in any other source. "historicalEntries" lists entries in historical dictionaries (e.g. Đại Nam Quấc âm tự vị, 1895) that print this character — summaries only. Pass an entryId to lookup_dictionary_entry for the original wording and its subentries. Use for Vietnamese Hán Nôm. Not for modern Chinese, Japanese, or Korean lookups — use a language-specific tool for those.	ALWAYS invoke this before stating any reading, meaning, or variant of a Chữ Nôm (喃) or Hán (漢) character.

`lookup_dictionary_entry`Use this to retrieve an original entry from a historical Vietnamese dictionary such as Đại Nam Quấc âm tự vị (Huình-Tịnh Paulus Của, 1895–96). Search by Quốc-ngữ headword when you do not know the character, or pass an entryId returned by lookup_character or by a headword search to retrieve the source-faithful entry and its ordered subentries. Do not infer missing glyphs or modernize historical spelling. Pass EXACTLY ONE of entryId or headword — never both, never neither. Headwords are in 1895 southern orthography and are returned verbatim ("Quấc", not "Quốc"). "typeMarker" is the printed marker as set: "n." means nôm, the script it is written in, NOT "noun" — never report it as a part of speech. A subentry with no "han" printed none in the source; do not construct one. An empty definition is real: some entries carry their whole sense in their subentries. Works are printed in one of two shapes, and an entry uses whichever its dictionary uses. Some print SUBENTRIES — compound phrases under a headword. Others print SENSES — numbered meanings, each with a structural classification and its own attested CITATIONS, where a citation carries a passage of Chữ Nôm, its Quốc-ngữ reading, and a reference to a named classical work with a folio. Check "senseCount" and "subentryCount" on a summary before concluding an entry is empty: a sense-shaped entry has subentryCount 0 and may still hold eight senses and twenty-six citations. Citations are evidence, and the strongest thing this tool returns. Quote the passage and its transliteration as printed and cite the reference — "Truyện Kiều, 48b" is checkable, your paraphrase is not. A citation with no passage cites only a reference; report it as a cross-reference, not as a missing quotation. "senses" is never paged: if the field is there, it is all of them. Subentries are PAGED. Read "subentries.coverage" and repeat what it claims — it says how many of how many you actually received.

`search_corpus`Find Hán Nôm characters by their Vietnamese reading (quốc ngữ, e.g. "trăng") or by Vietnamese meaning. Use when you need to discover which characters correspond to a Vietnamese word, then call lookup_character on the result for full detail. Each result reports what actually matched — "matchedOn" is "reading" or "meaning", and "match" carries the exact reading or the definition containing your query, with its source. Do not treat that definition as the character's only sense; call lookup_character for the rest. Returns at most 20 characters per call, with no pagination. This dictionary's readings and meanings come from sources under CC BY-SA 4.0, so bulk redistribution carries ShareAlike obligations — the cap keeps ordinary use well inside that. Cite the source on each result rather than presenting the corpus as your own.	Find Hán Nôm characters by their Vietnamese reading (quốc ngữ, e.g. "trăng") or by Vietnamese meaning.
