What extra function does it add to the event?
Ý nghĩa
A helping element that adds tense, aspect, modality, voice, negation, question formation, or grammatical support to an event.

Ví dụ
be|have|do|can|will|must
is going|has eaten|do not know|can swim

Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
