• pronoun

1

(archaic) That or those belonging to or associated with thee; the singular second-person possessive pronoun equivalent to modern 'yours'.

• adjective

1

(archaic) Belonging to or associated with thee (used instead of 'thy' before a vowel sound or silent 'h', or occasionally following a noun for stylistic emphasis).

Example

Word Nuance & Usage

Like the indefinite articles 'a' and 'an', the possessive determiner 'thine' historically alternated with 'thy': 'thine' was used before words beginning with a vowel sound or a silent 'h' (e.g., 'thine eyes', 'thine honor'), while 'thy' was used before consonant sounds. As a standalone possessive pronoun (equivalent to modern 'yours'), 'thine' is always used regardless of surrounding sounds.

Word Origin & Etymology

From Old English þīn, the genitive form of þū ('thou'), descending from Proto-Germanic *þīnaz.
