• English: y-, a-, i- (obsolete)

• Not productive in Modern English.
• This prefix represents a common Germanic collective prefix, as well as a perfective prefix which was used to form past participles. Already by the Old English period such participles could be used with or without it, and as it passed into Middle English forms y-, i-, and ȝe-, it became less productive. The prefix was later adopted as a conscious archaism by some writers such as Edmund Spenser, who prepended it to existing past participles.

• ẏ, Middle English abbreviation for þe
• Middle English, y- (prefix) is often confused with ye (pronoun) or with þe (the) or ye (article, definite) and the thorn þ due to typographic variation:
  • ȝe- / y- is pronounced /ɪ/, consistent with the Old English pronunciation of ge- as /je/, /jə/ and is a verbal prefix dropped in modern English.
  • In Middle English, the article ye or y^e is pronounced thē, thə and is effectively an alternate spelling of þe (the).
