Kith and kin

Kith and kin is an English adage meaning "those who are close to your heart." Kith is an obsolete word meaning "children", while kin is a shortened form of kinfolk, meaning "family." The phrase was coined by Shakespeare in the play Hamlet, in which he puts a twist on the then-current English idiom kith and make up by having the melancholy Dane say that Claudius and Gertrude did "a little more than kith."
