Morphology

keep + to + oneself

The meaning 'to be private or reserved' is directly derivable from combining 'keep' (retain/stay) with 'to oneself' (toward one's own person), which signals holding back from others. This is a common reflexive/compositional pattern found across languages, so a B1 learner who knows the constituent words should readily infer the meaning.

Etymology

Keep to oneself comes from the simple image of a person holding things close and not giving them away, where keep means to hold and oneself means yourself. So, it now means 'to be private' or 'not share your thoughts and feelings'.
