3.1. Understanding the Verb ‘Fly’

3.2. What is the Past Tense of ‘Fly’?

The verb ‘fly’ has two important past forms:

  • Simple Past: flew
  • Past Participle: flown

‘Flew’ is used to describe a completed action in the past (e.g., “She flew to Paris yesterday”).

‘Flown’ is used with auxiliary verbs to form perfect tenses (e.g., “She has flown many times”) or in passive voice (e.g., “The plane was flown by the pilot”).

Mastering these two forms helps with narration, storytelling, reports, and everyday communication.

3.3. Why ‘Fly’ is Irregular

Regular verbs add -ed in the past (e.g., walk → walked), but ‘fly’ changes to flew and flown.

This irregularity stems from Old English roots. Historically, many strong verbs formed their past by vowel changes (ablaut), not suffixes. Over time, some verbs became regular, but ‘fly’ retained its irregular pattern.
