search_latinLook a Latin word up on Wiktionary and return its senses plus full declension/conjugation tables — attested content, not invented. Any form of the word works; an inflected query is resolved to its lemma automatically (via previously cached paradigms or the Morpheus analyzer) and the result notes the resolution. Returns Markdown. Results are cached server-side; first-time queries reach the live upstream politely and calls are rate limited — on a rate-limit error, wait a few seconds and retry. Content is from en.wiktionary.org (CC BY-SA 4.0 — attribute and share alike if republished).
get_inflectionsFetch the full declension (nominals) or conjugation (verbs) table for a lemma identified by a search result's inflection handle (vards_id + word_class). Use this only when a search ran without inline forms or left a match un-expanded — a default search already returns each match's table inline. Returns Markdown; content from en.wiktionary.org (CC BY-SA 4.0).
lemmatize_latinAnalyze one inflected Latin form with the Morpheus morphological analyzer: its lemma(s) plus the grammatical reading (person, number, tense, mood, voice, case…). Useful when you want the morphology itself — for the dictionary entry, search_latin already resolves inflected queries on its own. Results are cached server-side. Analyses via the Perseids Morpheus service.
