(Nathanael West, Miss Lonelyhearts) - "We find participial phrases in three positions. Participial phrases can come before a main clause (initial position), after a noun phrase they are modifying (middle position), or after a main clause (final position). . . .
What kind of punctuation do we need to use when participial phrases occur in different positions?
- When the participial phrase comes before a main clause, it is followed by a comma.
- When the participial phrase follows a main clause, a comma must come before the participial phrase.
- When the participial phrase occurs in mid-sentence position, we use two commas. One comma comes before the participial phrase and the other comes after it.
