Passive voice is used when the focus is on the action. It is not important or not known, however, who or what is performing the action.
Example: My bike was stolen.
In the example above, the focus is on the fact that my bike was stolen. I do not know, however, who did it.
Sometimes a statement in passive is more polite than active voice, as the following example shows:
Example: A mistake was made.
In this case, I focus on the fact that a mistake was made, but I do not blame anyone (e.g. You have made a mistake.).
Form of Passive
Subject + finite form of to be + Past Participle (3rd column of irregular verbs)
Example: A letter was written.
When rewriting active sentences in passive voice, note the following:
- the object of the active sentence becomes the subject of the passive sentence
- the finite form of the verb is changed (to be + past participle)
- the subject of the active sentence becomes the object of the passive sentence (or is dropped)
Examples of Passive 
| Tense | Subject | Verb | Object | |
|---|---|---|---|---|
| Simple Present | Active: | Rita | writes | a letter. |
| Passive: | A letter | is written | by Rita. | |
| Simple Past | Active: | Rita | wrote | a letter. |
| Passive: | A letter | was written | by Rita. | |
| Present Perfect | Active: | Rita | has written | a letter. |

Verb Conjugation & Spelling
We form the present tense using the base form of the infinitive (without the TO).
In general, in the third person we add 'S' in the third person.
| Subject | Verb | The Rest of the sentence |
|---|---|---|
| I / you / we / they | speak / learn | English at home |
| he / she / it | speaks / learns | English at home |
The spelling for the verb in the third person differs depending on the ending of that verb:
1. For verbs that end in -O, -CH, -SH, -SS, -X, or -Z we add -ES in the third person.
- go – goes
- catch – catches
- wash – washes
- kiss – kisses
- fix – fixes
- buzz – buzzes
2. For verbs that end in a consonant + Y, we remove the Y and add -IES.
- marry – marries
- study – studies
- carry – carries
- worry – worries
NOTE: For verbs that end in a vowel + Y, we just add -S.
- play – plays
- enjoy – enjoys
- say – says
Negative Contractions
