Is “fly” a regular or irregular verb?

The verb fly is irregular. The difference between regular and irregular verbs is that regular verbs end in –ed in their past verb forms. Irregular verbs end in something other than –ed. As fly ends in something other than –ed in both its past tense forms (flew/flown), this makes it irregular. Here’s a chart of other irregular verbs that, like fly, use two forms in the past tense:

When to use flew vs. flown

Compare these sentences:

The pilot flew overnight from Paris to New York. (simple past)

I was exhausted because I had flown all night. (past perfect)

The first sentence describes an action that occurred and was completed fully in the past. The second sentence also describes something that took place and was completed in the past, but it differs from the first sentence in numerous ways. Try to read this next sentence out loud:

I was exhausted because I flown all night.

This does not make sense in English. It’s clear by reading the sentence out loud that a word is missing, and that word (aka verb) is had, the past tense of the verb have. Because flown is a participle, it pairs with helping verbs (such as has, have and so forth). Think of participles as a little bit verb, and a little bit adjective, but not one or the other entirely. Now try to read this sentence out loud:

I was exhausted because I had flown all night.

The sentence makes sense because we included the auxiliary/helping verb have, in its past participle form, had. The present of had + flown indicates the past perfect tense.
