The Origin of Sung or Sang

The verb sing is very old. It comes from Old English singan. Many old English verbs change vowels in past forms. This pattern is called a strong verb pattern.

Examples of similar verbs:

• ring → rang → rung
• drink → drank → drunk
• begin → began → begun

Like these verbs:

• sing → sang → sung

The vowel changes show tense. Over time, English kept this pattern. That is why both words exist. They are not spelling differences. They show different grammar roles.
