Verbs ending in -e simply add -d to form the past tense. This is the most straightforward regular rule.
Incubate is regular. It follows the -d Addition rule.
Use past time markers: "Yesterday, she incubated to the store."
No. Use "did not incubate" (not "did not incubated").
The verb incubate follows the standard English past tense conjugation rule. When forming the past tense, incubate becomes incubated. This follows the -d Addition pattern, which is one of the most common conjugation rules in English.
Understanding why incubate becomes incubated helps with spelling and pronunciation. Verbs ending in -e simply add -d to form the past tense. This is the most straightforward regular rule.
When using incubated in writing, remember that it functions as a past tense verb and typically appears with time markers like yesterday, last week, or ago. For example: "Yesterday, she incubated to the store." The past tense form does not change based on the subject — I incubated, you incubated, he/she incubated, we incubated, they incubated.
