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