What are the words that does not change in spelling when it becomes a past tense?

You're asking about verbs that don't change spelling in the past tense. These are called irregular verbs, and they're a bit of a pain in the neck for English language learners!

Here are some examples of irregular verbs that don't change their spelling in the past tense:

* cut: I cut the cake.

* put: I put the book on the table.

* hit: He hit the ball.

* let: She let me go.

* set: They set the table.

* shut: He shut the door.

* hurt: It hurt my feelings.

Important note: Just because a verb doesn't change spelling in the past tense doesn't mean it's always pronounced the same. For example, "cut" and "put" are pronounced differently in the past tense.
