the.com/acquaintance

a friend you haven't decided to trust yet, lingering politely in your social waiting room

means a person you know slightly or somewhat, but who isn't a close friend.

from From Old French acointance, built on the verb acointier, 'to make known,' which traces back to Latin accognoscere — ad- ('to') plus cognoscere ('to know,' the same root behind 'recognize' and 'cognition'). So baked right into the word is the idea of someone you've merely come to know, not someone you've come to love.
