29/8/19 REASON
Reason can be followed by why… or that
  • The reason why I came here was to be with my family.
  • The main reason why he lost his job was that he was drank.
  • Do you know the reason that they’re closing the factory?
In an informal style, why/that is often left out.
  • The reason she doesn’t like me is that I make her nervous.
  • The reason I’m asking is that I’m short of money.
The normal preposition after reason is for.
  • What’s the real reason for your depression? (NOT …reason of your depression?)
Some people consider it incorrect to use a because-clause as complement after reason (as in Sorry I’m late – the reason is because I overslept.).
