Before making a move in a game like chess, a player thinks about what will happen if he or she makes the move. The player does not actually make the move, but thinks about it instead. No move is made until the player considers several hypothetical moves. The player is analyzing options based on cause-effect relationships.
We express hypothetical situations with the preterit. The past tense verb form expresses distance or remoteness from reality rather than a past time frame. Hypothetical, unreal conditional, or irrealis indicates that an action or state-of-being is not a fact.
| STRATEGY – IN ORDER TO |
|---|
A strategy states a well-thought out but imaginary action taken on something or someone. The strategy can be expressed hypothetically as cause-effect: the strategy in the if-clause and the imagined effect in the result clause. |

|
|
| CONDITIONAL – UNREAL | |
|---|---|
The preterit is used in the If-clause. The preterit "distances" the situation from present reality ("irrealis"), and it expresses an imaginary or hypothetical situation. A modal such as would or could is used in the result-clause. |
|
If I moved my pawn forward, |
then I could take his bishop. present unreal |
If I slid my castle out of the way, |
then his queen might not take it. present unreal |
If I checkmated his king, |
my friend would be mad. present unreal |
If I were a good friend, |
I would let my friend win once in a while. present unreal |
preterit (n.) – a past tense verb form; past or past perfect
hypothetical (adj.) – assumed by hypothesis (theory); unreal conditions or situations
in order – for the purpose of
| STATEMENT | |
|---|---|
We use special verbs with if when we are talking about situations that we imagine; that is, things that probably will not happen. The unreal statement includes the preterit. The result clause includes a would or could modal form. |
|
| CONDITION | RESULT — WOULD / COULD |
If I were/was a millionaire, |
I would buy a private jet. |
If I were/was a millionaire, |
I could buy a private jet. |
If I could choose anything, |
I would buy a house. |
If I could choose anything, |
I would buy a house. |
Were I a millionaire, |
I could buy a house. |
| NEGATIVE / QUESTION | |
|---|---|
A negative is formed by placing not after the verb in the hypothetical clause or in the other clause. A question is formed by inverting the subject and auxiliary verb (would or could) in the result clause. |
|
| CONDITION | WOULD OR COULD NOT |
If I were/was a millionaire, (I am not) |
I wouldn't travel on a commercial airline. |
If I weren't /wasn't a millionaire, (I am) |
I would have to travel like everyone else. |
If I could vacation anywhere, |
I wouldn't stay here. |
If you were a millionaire, |
could you stop working? |
If you could choose, |
would you move away? |
¹repeating could is awkward
preterit (n.) – a past tense verb form; past or past perfect
commercial airline – an airline used by the public, not private
was / were – We often use were instead of was after if. Both was and were are used in formal English, but only was is used in informal English. If I were you... Were is a subjunctive verb form.
| PRESENT / FUTURE CONDITION | HYPOTHETICAL RESULTING ACTION |
|---|---|
A future hypothetical is expressed with be going (not will) in an if-clause. Were (formal) or was (informal) is used for 1st and 3rd person singular in the if-clause Either of the clauses on the left can be mixed with the clauses on the right. |
The resulting action is imaginary. Note that phrasing for present and future tense are the same. Also note "be going to" and "go" expressions (go shopping/ go fishing/ go swimming) can add to the confusion. |
| FUTURE HYPOTHETICAL | RESULT CLAUSE |
If it were going to rain soon, (later today) |
I wouldn't plan on walking the dogs later. future I would be walking the dogs now. present I would have walked the dogs already. past |
If we were going to go to the movies, (later today) |
we would buy our tickets in advance. future we would be online buying our tickets. future we would be getting ready now. present we would have left already. past |
| PRESENT HYPOTHETICAL | RESULT CLAUSE |
If it were raining now, |
I would plan on walking the dogs later. future I wouldn't be walking the dogs now. present I would have brought the dogs inside already. past |
If we were going to the movies, (now) |
we would buy our tickets in advance. future we would be buying our tickets online. future we would be getting ready now. present we would have left already. past
