Auxiliary Engine
What extra function does it add to the event?
意味
A helping element that adds tense, aspect, modality, voice, negation, question formation, or grammatical support to an event.
見分け方
Look for small verbs that do not carry the main event meaning but change how it works.
例
be|have|do|can|will|must
is going|has eaten|do not know|can swim
She has finished her work.

Function coding choices suffix on verb: walk-ed aux word: has eaten modal aux: can swim support aux: do not know Check: which jobs need AUX?
言語別ビュー
母語の仕組み
Japanese uses auxiliary-like endings and light verbs, but not English-style auxiliaries for tense questions.
宿題を終えてしまった。
I ended up finishing the homework.
学習言語では
English uses auxiliaries for questions, negatives, emphasis, tense, aspect, passive, and modality.
Do you understand?
do = auxiliary engine
Learners often omit do-support, misuse be/have, or stack auxiliaries incorrectly.
Good transfer potential
This block behaves relatively similarly, so you can transfer intuition more safely between the two languages.
