3. How can we transform a verb into Past ?
In case it is a
Regular Verb
we just add

The
ED
Suffixe
Example:
Work
Play
Enjoy
Worked
Played
Enjoyed

4. Exceptions in spelling
when adding ed
Example
After a final E you only need to
add D
Love – LOVED
When letter L or T goes as final
consonant after a vowel MUST
be doubled
Admit – ADMITTED
Travel – TRAVELLED
Final Y after a consonant must
change to I and then you add
the ED suffixe.
Hurry – HURRIED

hand I know
how to
recognize a
verb in its
Past tense
But on the
other hand, I
still don’t
know about

6. There are plenty of Irregular Verbs; NONE OF
THEM CAN BE TRANSFORMED BY
ADDING JUST  ED.
