Other forms: familiars
Something familiar is something you already know without being told — a face in the crowd you have seen before, a song you can hum without remembering where you learned it, the particular smell of your own kitchen.
It runs two ways and this is where learners slip: a thing is familiar to you, and you are familiar with a thing. The name is familiar to me. Are you familiar with the software? It also carries a warning sense — being too familiar with someone means treating them as though you know them far better than you do, and it is not a compliment. In old stories a familiar is a noun: the animal that keeps a witch company, a cat or a toad or a crow.

Latin familiāris meant belonging to the household — the servants, the people always about the place. What is familiar is what lives in your house. Family and familial are the same word, and English had a word of its own for it, hīwcūþ, before the Latin one pushed it out.
