Answer: SIMPLE PAST TENSE OF VERB; Typically, you would form the past tense as follows: Take the root form of the verb (the one you will find in our amazing dictionary) and add –ed to the end. If the verb ends in -e, you would just add a -d. For example, the simple past tense of look is looked, and the simple past tense of ignite is ignited.

 PAST PERPECT TENSE OF VERB; The past perfect tense is formed by using the word had followed by the past participle of the verb. For regular verbs, the past participle is a form of the verb that ends in -ed or -d. For example, the past participle of watch is watched

THIS IS THE DEFFERENCE; These two tenses are both used to talk about things that happened in the past. However we use past perfect to talk about something that happened before another action in the past, which is usually expressed by the past simple.
