The simple past tense is used to talk about finished past events or states. It is formed by adding "-ed" to regular verbs or making other changes like doubling consonants. Some examples of its uses include talking about things that happened at a specific time in the past or with a frequency modifier. The grammatical structure is subject + verb in past form + complement. To make negatives, "didn't" or "did not" is used before the verb, except for forms of "to be" which use "wasn't/were not". Questions are formed by using "did" before the subject and verb.

2. DEFINITION OF THE SIMPLE PAST
TENSE
The simple past tense, is the most common way of talking about past
events or states which have finished. It is often used with past time
references. It is usually formed by adding -ED to the verb.
A past event could be one thing that happened in the past, or a repeated
thing:
 I stopped at a zebra crossing.
 We played tennis every day in August.
A state is a situation without an action happening:
 We stayed at my grandparents' house last summer.

3. We always use the simple past when something
happened, so it is associated with certain past
time expressions:
Frequency: often, sometimes, always.
I often brought my lunch to school.
A definite point in time: last week, when I was a child, yesterday.
We saw a good film last week.
An indefinite point in time: the other day, ages ago, a long time ago
People lived in caves a long time ago.

4. • If a word ends in an E we just add the D at the end of the
verb.
Example> move-moved
Live lived
Love loved
Smile smiled
Dance danced

5. • verbs ending in a consonant Y take ied in the simple past. This means
that we change the letter Y for an i
Examples
marry = married
carry = carried
study = studied
the only exception to this rule is the word play
Example paly-played

6. • If the word ends in a Consonant, and before is a vowel, we double
the final consonant and add ED.
Example> travel-travelled
Stop stopped
Admit admitted
Plan planned
Refer referred
Commit committed

7. GRAMMATICAL STRUCTURE
 Subject+verb (in past form)+complement.
Example:
 She played soccer yesterday.
 They studied math last week.

8. FORMING A NEGATIVE
•Negatives in the simple past are formed by
adding didn't (informal) or did not (formal)
before the simple form of the verb. The verb
BE is an exception to this; in the case of BE,
we just add n't (informal) or not (formal) after
"was" or "were":
