T

2. Adjusting the space between two letters so "AV" doesn't look like a car crash
4. the enclosed/partially enclosed space inside a bowl (b, o, g). Directly completes the BOWL entry conceptually.
6. When two letters get too close and just... merge, like fi or fl
8. The part of a lowercase letter that climbs above the x-height, like on a b or d
11. the horizontal stroke on A, H, e, f, t.
14. Type that leans in, like it's telling you a secret
15. Letterforms built from disconnected shapes so a physical stencil could work
16. The short dash that breaks a word across a line or joins compound words
17. The part of a lowercase letter that dips below the baseline, like on a g or y

1. the curved or angled end of a stroke that isn't a serif (as in c, a, r).
3. The curved part of a letter that encloses a counter, as in b, p, or g
5. short (3), the small stroke off the bowl of a lowercase g. Good for grid density.
7. The pointy top where two strokes meet, like on an A or M
9. The little foot at the end of a letter stroke, like this text (probably) has
10. A flourish that shows off, usually on a capital or an italic tail
12. The main curved stroke of an S
13. the dot over i or j. Obscure enough to feel like a reward for people who actually know type, which fits your "obsessed with typography" bar.
