ejus

Ejus is a Latin genitive singular form of the third‑person pronoun is, ea, id, used to indicate possession and translate as “of him,” “of her,” or “of it.” In classical Latin the standard spelling is eius; ejus is a variant produced in some medieval manuscripts and in certain modern Latin texts. Both spellings serve the same grammatical function and typically precede the noun they modify, as in eius filius (“his son”) or ejus nominis (“of his name”).

In usage, ejus/eius marks possession between the pronominal form and a following noun. The genitive pronoun can pair with any noun to express a relationship of ownership or association, for example eius or ejus mens in phrases referring to “his/its mind” or “her name,” depending on the referent.

A notable derivative in Latin is the compound phrase ejusdem (or eiusdem), meaning “of the same.” This appears in the well-known legal expression ejusdem generis, literally “of the same kind,” used in statutory interpretation to indicate that a general term should be understood in light of the specific terms with which it is grouped. Variants in spelling (ejusdem vs eiusdem) reflect orthographic differences rather than distinct meanings.

In English-language scholarship and law, ejus is encountered mainly within Latin quotations or phrases. Outside those contexts, Latin pronouns are usually presented in their standard classical forms (eius), but ejus may appear in texts that preserve medieval or regional spellings. See also is, ea, id; eiusdem generis.
