The Origin of Overlaid or Overlayed
The confusion between overlaid and overlayed comes from English verb conjugation rules.
Word History
The verb overlay comes from combining two words:
- Over
- Lay
Since the verb “lay” has an irregular past tense (laid), the verb overlay follows the same pattern.
This creates:
- Present Tense: Overlay
- Past Tense: Overlaid
- Past Participle: Overlaid
Why the Confusion Happens
Many writers assume every English verb follows a regular pattern.
Examples of regular verbs:
- Walk → Walked
- Play → Played
- Jump → Jumped
However, overlay belongs to a group of irregular verbs.
Understanding the Grammar Rule
The easiest way to remember the rule is to focus on the base verb.
