Tangentially is defined as briefly mentioning a subject but not going into it in detail, or is defined as going off in a different direction.
in the case of
briefly mentioning a subject but not going into it in detail the topic/subject need not be related at all (it sounds like).
What about in the case fo:
is defined as going off in a different direction. Does the fact that it's going off in a different direction imply that it at least starts out connected/related to the original (starting point) subject (as it does in the geometry sense of tangential)? Or does it permit "jumping" to another topic (in another direction) without being related/connected at all??
I don't think I like this definition very much. It doesn't quite fit the sense I'm trying to use it for in my tag:
tangentially related content (aside)
Ah, here's a definition that matches what I thought it meant (one of the senses anyway): https://hyp.is/3Bn2bpZ7Eeu3Ok8vg03AVA/www.merriam-webster.com/dictionary/tangential
