Inherited from Vulgar Latin *ipsus or Latin ipsum, masculine accusative of ipse, with a nasal infix from Latin (compare attested inpsuius). Cognate with Aromanian nãs, Old French esse, Italian esso, Portuguese esse, Spanish ese, see more cognates at ipse.
îns m or n (feminine singular însă, masculine plural înși, feminine and neuter plural înse)
No longer used today in its original form, in which it was a pronoun that could serve as an adjective, though has preserved its meaning articulated in compounds like printr-însul (with printru). Now it is found mostly in derivatives of the older form, such as ins (“person, individual”), dânsul, and together with forms of personal pronouns, such as in însuși (“himself, itself”).
