The tense of a verb suggests the time of its action-present, past, or future. We rely on the past tense to show that an action has already been completed.
Adding -d or -ed to Form the Past Tense
In the following sentences, the verbs in bold are in the past tense:
- Wallace moved into his new house last Saturday.
Yesterday I visited him for tea.
Both move and visit are called regular verbs because they have the same past-tense ending of -ed.
If the present form of a regular verb ends in -e, we add -d to form the past tense:
- Wallace and Gromit move frequently. (present tense)
Wallace and Gromit moved into their new house last Saturday. (past tense)
If the present form of a regular verb ends in a letter other than -e, we usually add -ed to form the past tense:
- I visit Wallace and Gromit every Tuesday evening. (present tense)
Yesterday I visited them for tea. (past tense)
Note that a spelling rule comes into play with verbs ending in -y. If the present form of a regular verb ends in -y preceded by a consonant (for example, cry, fry, try, carry), change the y to i and add -ed to form the past tense (cried, fried, tried, carried):
- Wallace and Gromit carry the cheese and crackers into the kitchen. (present tense)
Wallace and Gromit carried the cheese and crackers into the kitchen. (past tense)
Because all regular verbs have the same -ed ending in the past tense no matter what the subject is, subject-verb agreement is not a problem.
The Different Sounds of the -ed Ending
Don't let the sound of an -ed ending ever trick you into making a spelling error when you form the past tense. While we do hear a d sound at the end of some verbs (for example, moved and visited), we hear a t sound at the end of others (promised, laughed). Also, if you have a habit when you speak of clipping off word endings, don't do this when you write. No matter what sound you hear or fail to hear when you pronounce a regular verb in the past tense, be careful when you write to add -d or -ed at the end.
