Archaic and Poetic Uses

In older English texts and poetry, "of" occasionally appears in constructions that blur the line between preposition and other roles. For example:

Informal or Dialectal Uses

In some dialects and informal speech, "of" is sometimes used in place of "have" in auxiliary constructions, such as:

• "I could of done that."
