The Origin of Begun or Began

Both words come from the Old English verb “beginnan.” Over time, English kept two forms:

• Began → Past tense
• Begun → Past participle

English often changes vowels to show tense. This is called a strong verb pattern.

Other examples follow the same pattern:

• Begin – Began – Begun
• Sing – Sang – Sung
• Drink – Drank – Drunk

The vowel change helps show time without adding “-ed.”
