Pronunciation : His
Part of Speech : pron.
Etymology : [AS. his of him, his, gen. masc. & neut. of h, neut. hit. See He.]
Definition : 1. Belonging or pertaining to him; -- used as a pronominal adjective or adjective pronoun; as, tell John his papers are ready; formerly used also for its, but this use is now obsolete. No comfortable star did lend his light. Shak. Who can impress the forest, bid the tree Unfix his earth-bound root Shak.

Note: Also formerly used in connection with a noun simply as a sign of the possessive. "The king his son." Shak. "By young Telemachus his blooming years." Pope. This his is probably a corruption of the old possessive ending -is or -es, which, being written as a separate word, was at length confounded with the pronoun his.

2. The possessive of he; as, the book is his. "The sea is his, and he made it." Ps. xcv. 5.
