↑ 1.01.1The genitives my, mine, thy, and thine are used as possessive adjectives before a noun, or as possessive pronouns without a noun. All four forms are used as possessive adjectives: mine and thine are used before nouns beginning in a vowel sound, or before nouns beginning in the letter h, which was usually silent (e.g. thine eyes and mine heart, which was pronounced as mine art) and my and thy before consonants (thy mother, my love). However, only mine and thine are used as possessive pronouns, as in it is thine and they were mine (not *they were my).
↑ 2.02.1From the early Early Modern English period up until the 17th century, his was the possessive of the third-person neuter it as well as of the third-person masculine he. Genitive "it" appears once in the 1611 King James Bible (Leviticus 25:5) as groweth of it owne accord.
