Regular verbs form the simple past tense by adding "-ed" to the infinitive. Some consonant changes may occur depending on the spelling of the verb. Irregular verbs have unpredictable changes in form between the infinitive, simple past, and past participle. Common irregular verbs include "be, go, see, come" among many others. Time expressions like "yesterday" and "last week" indicate that the simple past tense should be used.

Adding -ed to Regular Verbs
1. . Regular verbs
infinitive + -ed
Add -ed with regular verbs
Sometimes there are exceptions in spelling when adding -ed.
1) consonant after short, stressed vowel at the end of the word
Double the consonant.
stop – stopped
swap - swapped
If the consonant is not stressed, we do not double it:
benefit - benefited (Here we stress the first 'e', not the 'i'.) In British English we double one
-l at the end of the word:
travel - travelled
2) one -e at the end of the word add only d.
love – loved
save – saved
3) verbs ending in -y
verbs ending in 'y' preceded by a vowel (a, e, i, o, u): Add -ed.
Example:
I play - he played
verbs ending in 'y' preceded by a consonant: Change 'y' to 'i' Then add -ed.
Example:
I hurry - he hurried
2. Pronunciation of the ending -ed in the Simple Past
In the Simple Past we add -ed to regular verbs. Be careful pronuncing the verbs:
1) verbs ending in -ed preceded by a voiceless consonant [p, k, f, ʃ , ʧ , s, θ]
-> speak [t].
The -e is silent. Example: I stop - I stopped [stɒ pt]
2) verbs ending in -ed preceded by a voiced consonant [b, g, v, ʒ , ʤ , z, ð, l, m, n] or a
vowel
-> speak [d].
The -e is silent. Example: I clean - I cleaned [kli:nd]
3) verbs ending in -ed preceded by [t] or [d]
-> speak [ɪ d].
The -e changes to [ɪ ]. Example: I visit - I visited [vɪ zɪ tɪ d]

The trend, in English, and especially in American English, is to standardize the irregular
verbs. We do not foresee all the irregular verbs ever being standardized, but some of the
more minor variations in less commonly used words will probably disappear in the next
genration or two.
The following English irregular verbs are now obsolete and use the standard past and
participle forms (-ed).
infinitive simple past past participle
burn burnt burnt
dream dreamt dreamt
11. learn learnt learnt
smell smelt smelt
spell spelt spelt
