Synonym discussion
Sense: noun/1
All five words describe a lack of emotional engagement, but they differ in strength and nuance. Indifference is the most neutral term — it simply means not caring one way or the other. Apathy is heavier: it suggests a troubling emotional emptiness, often in situations where feeling is expected, such as public apathy toward a crisis. Unconcern is lighter and more situation-specific: a person might feel unconcerned about a minor risk without being generally apathetic. Detachment implies a deliberate choice to stay emotionally separate, which can be positive (a doctor's professional detachment) or negative (emotional detachment from a partner). Disinterest overlaps with indifference but also carries a formal meaning of impartiality — a judge's disinterest is a virtue, whereas their indifference would be a flaw. In everyday usage, indifference is the safest choice for general lack of concern.

Etymology
Indifference came into English from French 'indifférence', which came from Latin 'indifferentia' meaning 'no difference'. The Latin word combined 'in-' (not) with 'differens' (differing). The original idea was that if two things seem the same to you, you have no reason to prefer one over the other — so you don't care. Over time, the meaning shifted from 'not seeing a difference' to 'not caring at all'.
