affinity
Synonym discussion
Sense: noun/1
All five words suggest some kind of connection, but they point to different kinds. 'Affinity' is the broadest useful word here: it describes a natural pull towards a person, group, art form, or idea, often because something feels like a good match for you. 'Liking' is simpler and weaker; you can like jazz without feeling any deeper bond with it. 'Sympathy' stresses understanding another person's feelings, especially in a difficult situation. 'Rapport' is an easy relationship built through conversation and trust. 'Kinship' often sounds deeper or more lasting, and may suggest a shared spirit or background. You might like a teacher's class on day one, feel affinity with her after hearing her values, and build rapport after working together all term.

Etymology
The word came into English through French from Latin 'affinitas'. In Latin it first referred to closeness, especially family connection by marriage, and was built from 'affinis', meaning 'bordering on' or 'related'. English later widened the idea from family ties to a natural attraction between people or things, and then to close resemblance between things.
