ipse

From Latin ipse.

ipse

1. himself; herself; itself

• ipsus (Old Latin)

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

In Old Latin when both parts were inflected, a glide consonant p was inserted in the form *eum-sum, yielding 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]
