💡Pro Grammar Tip

Remember that participles need a partner! The past participle “fed” is always paired with an auxiliary verb like ‘have’, ‘has’, or ‘had’ to form perfect tenses.

When to use simple past “fed” vs. past participle “fed”

He fed the cat before he left for work.

The cat had already been fed when he got home.

The participle form of a verb is not a tense on its own; it requires a helper verb to function correctly. In the second sentence, the auxiliary verb “had been” indicates that “fed” is being used as a past participle to form the past perfect tense in the passive voice. The simple past form, “fed,” stands alone to describe a completed action in the past and does not need an auxiliary.
