If something happens before a time or event, it happens earlier than that time or event.
You also use before when you are talking about the past and you want to refer to an earlier period of time. For example, if you are describing events that took place in 2010, you refer to 2009 as 'the year before'.
You use before last to refer to a period of time that came before the last one of its kind. For example, if today is Wednesday 18th September, you refer to Friday 13th September as 'last Friday', and Friday 6th September as 'the Friday before last'.
Before is sometimes used to mean in front of'. This is a formal or old-fashioned use. It is more common to use in front of with the same meaning.
You use before or in front of when you are talking about the order in which things appear in speech or writing. For example, if you are describing the spelling of the word 'friend', you can say that the letter 'i' comes before or in front of the letter 'e'.
If you are giving someone directions, and you say that one place is a certain distance before another place, you mean that they will come to the first place first. Don't use 'in front of' with this meaning.
