Conditionals: Three common patterns

Three common patterns

When learning English, it is common to discuss about the First, Second, and
Third Conditionals:

1. I'll buy you a coffee, if you borrow me your notes.
2. If we come today, we'd get the free gifts.
3. If you'd saved your words file, you wouldn't have lost all your words documents when your computer hanged.

Other patterns
The motive we have a discussion about those three is because they are the most common patterns, but there are many additional patterns in sentences with if;

1. It is common to use modals in conditionals:
If only you'd asked me, I would have lent you the book!
If you must make noise, do it outside, please.
If you want my point of view, I'd sell the motorbike and buy something more valuable.

2. Some conditionals use the present simple in both parts:

If the order comes in today, we get a bonus.
If it rains, the water comes in through the top.

3. You use the past simple in both parts to discuss about something that commonly happened in the past.
If it was sunny, we went down to the seaside with a picnic.
If it rained we stayed indoors and played poker cards.

A good rule
A good 'rule' is to avoid using would in the if-clause. This is almost always true.
