3. Definition Section: What Is the Past Tense of “Fly”?

3.1. The Verb “Fly”: Basic Meaning

The verb “fly” primarily means to move through the air using wings, as birds or insects do. It also extends to traveling by aircraft or operating something that moves through the air, such as drones or planes.

In a figurative sense, “fly” can indicate something moving swiftly or spreading quickly, as in “time flies” or “rumors fly”.

Importantly, “fly” is an irregular verb, meaning its past forms do not follow the standard “-ed” pattern.

3.2. Past Tense in English Grammar: Overview

The past tense expresses completed actions or states that occurred before now. English has several past tense forms:

  • Simple Past: describes completed actions at a specific past time (e.g., flew)
  • Past Continuous: describes ongoing actions in the past (e.g., was flying)
  • Past Perfect: describes actions completed before another past event (e.g., had flown)
  • Past Perfect Continuous: describes duration of an action up to another past moment (e.g., had been flying)

This article mainly focuses on the simple past and past participle forms of “fly”.

3.3. The Past Forms of “Fly”

4. Structural Breakdown: Forms and Formation

4.1. The Irregular Pattern of “Fly”

Unlike regular verbs, which simply add “-ed” (walk → walked), “fly” changes its internal vowel sounds to form its past forms:

  • fly → flew (simple past)
  • fly → flown (past participle)

This vowel change without an “-ed” ending classifies “fly” as an irregular verb.

4.2. Simple Past Form: “Flew”

The simple past of “fly” is “flew”.

Pronunciation: /fluː/ (rhymes with “blue”)

Usage: Use “flew” to describe a completed action in the past.

4.3. Past Participle Form: “Flown”

The past participle of “fly” is “flown”.

Pronunciation: /floʊn/ (rhymes with “known”)

Usage: Used in:

  • Perfect tenses: She has flown to many countries.
  • Passive voice: The drone was flown by a technician.

4.4. Present Participle and Simple Present for Context

For contrast, the present participle is “flying” (used in continuous tenses), and the simple present is “fly” or “flies” (for he/she/it).

  • I am flying tomorrow.
  • Birds fly south in winter.
