Morphology

affinity = affine (semi-transparent) = affin + ity

In scientific contexts 'affinity' denotes attraction or similarity, which is conceptually close to 'relatedness' and thus partially guessable from the base, though domain knowledge helps.

Etymology

Affinity is also used in science to mean a close attraction or fit, and it comes from Latin ad- 'to' and finis 'border', the idea of things meeting at a limit. That's why in chemistry or biology affinity describes how strongly one thing 'sticks to' or 'fits' another.
