irregular verbs: see 2nd column of irregular verbs
Example:
I spoke
irregular verbs: form of 'have' + 3rd column of irregular verbs
Example:
I / you / we / they have spoken
he / she / it has spoken
regular verbs: infinitive + ed
Example:
I worked
regular verbs: form of 'have' + infinitive + ed
Example:
I / you / we / they have worked
he / she / it has worked
Exceptions
Exceptions when adding 'ed':
  • when the final letter is e, only add d
    Example:
    love - loved
  • after a short, stressed vowel, the final consonant is doubled
    Example:
    admit - admitted
  • final l is always doubled in British English (not in American English)
    Example:
    travel - travelled
  • after a consonant, final y becomes i (but: not after a vowel)
    Example:
    worry - worried
    but: play - played
