ipsius

Ipsius is the genitive singular form of the Latin demonstrative and intensive pronoun ipse, ipsa, ipsum. It functions primarily as a possessive or emphatic element in phrases, conveying a close or reflexive sense such as “of the self,” “of that very,” or “of his/her/its own.” The genitive ipsius is used with nouns of any gender to express possession or emphasis.

In practical usage, ipsius attaches to a noun in a genitive construction. Examples include ipsius sententiae (of his own opinion), ipsius temporis (of that very time), and ipsius libri (of the book itself). The phrase can serve to stress the referent or to specify that something belongs to the person or thing designated by ipse. Because ipsius is the genitive form, it often appears in combination with other genitive elements or as part of a noun phrase that highlights the subject’s involvement or identity.

Historically, ipsius occurs in classical Latin prose and poetry as part of the broader system around ipse, which includes forms in other cases and numbers. It is commonly found in rhetorical or formal writing to reinforce emphasis, with the accompanying noun providing the concrete reference. In modern introductory Latin, ipsius is noted mainly as the genitive form of ipse, guiding learners in interpreting phrases that mean “of himself,” “of the very X,” or “of that X.”
