Overview

A single deinflection candidate: a base-form ‘term` reached from the input by applying `inflections` (transform names, ordered from the surface form inward to the dictionary form). `dictionary_form?` is true when the rule chain lands on a recognised dictionary form (a likely real lemma), useful for callers without their own dictionary to look the term up in.

Daidai.deinflect("食べてる")   # candidate base forms, each with named inflections;
                               # one is #<Daidai::Deinflection 食べる [-いる, -て]>
