Etymology Origin:
The word mental traces back to Latin mentalis, from mens (mind). It entered Middle English via Old French mental, retaining its core meaning of "pertaining to the mind." Over time, it gained colloquial uses (e.g., "crazy") and an archaic anatomical sense (chin-related), though the latter is obsolete. The root mens also appears in dementia ("away from mind") and mention ("to bring to mind").
