insë

himself

insë "himself" and "herself", 3rd person sg. personal reflexive pronoun, apparently covering both genders, e.g. *tiris insë "(s)he watches him/herself" (but apparently the general reflexive pronoun immo may also be used, and it may even be preferable since the cluster ns seems unusual for Quenya). Compare insa, the corresponding impersonal form. Insë is derived from earlier imsë, a form that was possibly also used in Quenya (unless "imse" in Tolkien's manuscript is intended as an etymological form only, though it is not asterisked) (VT47:37)
