Surface Forms

Morphology

incidentally = incidental (semi-transparent) = incident + al + ly

The adverbial formation from 'incidental' is regular, but the pragmatic usage 'by the way' is an extension of the adjective's sense and may not be fully predictable to learners.

Etymology

The word incidentally is also used like 'by the way' because it comes from the idea of a small event that 'falls into' a conversation. That's why when you say incidentally you are adding a side note or a new, not central topic.
