The particle "i" signals the past imperfect tense, the object of a transitive verb or the subject of a sentence formed with "neuter verbs" (a form of passive verb), as well as the prepositions in, at and from. Hope this helps! Marking me the brainiest and leave a thanks is much appreciated. ;)
Select the sentence containing the participle. Rocking gently, the mother put the infant to sleep. Rocking gently is a great way to put babies to sleep.
