Can a verb have ed on the end?

Yes, verbs can have "-ed" on the end. This is a common way to form the past tense and past participle of many verbs in English.

Here are some examples:

* Past Tense:

* walked

* talked

* played

* cooked

* Past Participle:

* walked (in "I have walked")

* talked (in "He has talked")

* played (in "They have played")

* cooked (in "She has cooked")

Not all verbs use "-ed" for the past tense or past participle. Some verbs have irregular forms (like "go" -> "went" -> "gone"). But, for a large number of verbs, "-ed" is the standard way to create the past tense and past participle.
