Verbs ending in a consonant followed by -y change the -y to -ied in the past tense form.
Modify is regular. It follows the -ied Conversion rule.
Use past time markers: "Yesterday, she modified to the store."
No. Use "did not modify" (not "did not modified").
The verb modify follows the standard English past tense conjugation rule. When forming the past tense, modify becomes modified. This follows the -ied Conversion pattern, which is one of the most common conjugation rules in English.
Understanding why modify becomes modified helps with spelling and pronunciation. Verbs ending in a consonant followed by -y change the -y to -ied in the past tense form.
When using modified 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 modified to the store." The past tense form does not change based on the subject — I modified, you modified, he/she modified, we modified, they modified.
