FORMATION

Conditionals are formed by two different clauses:

- It has a conditional conjunction (if - unless) at the beginning  

- Expresses the condition

​

THE MAIN CLAUSE  

- Expresses the consequence

IF or UNLESS?

The IF clause can be introduced by conditional linkers, such as IF or UNLESS.


IF - meaning "si"

UNLESS - meaning "a no ser que"
​

​

​

Change of conditional linkers

To rewrite a sentence using UNLESS instead of IF, we have to take into account the negative meaning of UNLESS, so the sign of the verb in the IF clause or the MAIN clause must be negative.
