  1. himself; herself; itself



Compounded from Proto-Indo-European *éy and *swé.

In Old Latin when both parts were inflected, from some form *eum-sum, one glide consonant p was inserted, eum-p-sum. From these accusative forms the stems -pso and -psā were extracted and adapted to the nominative forms, thus ipsus and eapsa. Ultimately the paradigm was assimilated to that of iste, ille, with only later in the history of Latin neuter ipsum becoming ipsud.[1]

See also Old Irish fessin, Gothic 𐍃𐌹𐌻𐌱𐌰 ‎(silba), and Hittite 𒀀𒉺𒅆𒆷 ‎(apasila).[2]


ipse (feminine ipsa, neuter ipsum)

  1. himself, herself, itself


Irregular: similar to first and second declensions but with genitive singular ending in "-īus" and dative singular ending in "-ī".
