First Conditional
Third Conditional
Second Conditional
This type of conditional is used
when the condition and result
is always true, such as
scientific facts.
Examples

for the future and in cases where
it is very likely that the condition will pass.
Examples

Note: We can change the order
of the sentences without
changing the meaning. Also, in
general with this type of
conditional, we can substitute
"if" for "when" without altering
the meaning.
Type 2 is used to express an unreal possibility
in the present, as a wish or a dream,
or for an action in the not so probable future.
Note: Some modal verbs can
be used instead of "will" to
change the probability or
express an opinion.
Examples
If I won the lottery, I would travel around the world.
/ I would travel around the world if I won the lottery.

Note: As in type 1, other modal
verbs can be used instead of
"would" to change the meaning
and possibility.
Unlike types 1 and 2, the third type of conditional
is used when we speak of a condition in the past
that has not happened.
Examples

/ I would have done things differently if I had known then what I know now.

meaning and probability.
