Simple Past
The simple past shows an action completed in the past.

| Present Perfect | She has sung before. |

The Origin of Sung or Sang
The verb sing has ancient roots.
It comes from the Old English word singan, meaning “to make musical sounds with the voice.”
Over centuries, English developed different verb forms.
Historical forms included:
- singan
- sang
- sungon
- sungen
English preserved these forms instead of adopting regular endings like “-ed.”
This history explains why modern English still uses:
- sing
- sang
- sung
Many Germanic languages follow similar patterns.
Examples:
- ring → rang → rung
- spring → sprang → sprung
These historical developments created today’s irregular verb system.
