Not careful about keeping secrets or respecting privacy; saying things that are tactless or inappropriate in social situations.
From Latin indiscretus (not separated), combining in- (not) + discretus (separated, distinct). It originally meant 'not distinguishing between things,' then evolved to mean not making proper distinctions about what should be said or hidden.
An indiscreet person can't seem to 'separate' private information from public conversation — they blur the line between what should stay hidden and what can be shared. This is why gossips are classically indiscreet; they don't distinguish between secrets and stories.
Historically applied more scrutinously to women's behavior and speech; 'discreet' carried gendered expectations around female modesty and silence.
Apply equally to all genders when describing tactlessness. Be conscious that silencing is often gendered.
