// morphology-fr.el - French morphology for the NLG engine.
|
||||
//
|
||||
// Implements fusional French verb conjugation, noun pluralization, gender
|
||||
// inference, article agreement, and interrogative inversion. Designed as a
|
||||
// companion to morphology.el and called by the engine when the language
|
||||
// profile code is "fr".
|
||||
//
|
||||
// Verb tenses covered: present, future, imparfait, passé composé.
|
||||
// Persons: first/second/third × singular/plural.
|
||||
// Verb groups: -er (regular), -ir (regular finir-type), -re (regular vendre-type)
|
||||
// + a core set of common irregular verbs.
|
||||
//
|
||||
// Liaison / elision notes:
|
||||
// - le/la → l' before vowel-initial nouns (handled in fr_agree_article)
|
||||
// - est-ce que can precede any statement for yes/no questions (fr_question_inversion)
|
||||
// - Inversion inserts -t- between vowel-final verb form and 3s pronoun: parle-t-il
|
||||
//
|

// Depends on: morphology.el (str_ends_with, str_slice, str_len helpers)
