With most verbs the past tense is formed by adding -ed:
Verb | Past tense |
| Call | Called |
| Want | Wanted |
| Like | Liked |
Exceptions in spelling when adding -ed:
| After a final -e only add -d: | love – loved |
| Final consonant after a short, stressed vowel or -l as a final consonant after a vowel is doubled: | admit – admitted travel – travelled |
| -y after a consonant becomes -i | hurry – hurried |
