Different ways of saying 'if'

'If' is a word that is often used to introduce conditional sentences. It's not the only way though. In 90 seconds Dan demonstrates five different expressions that have the same or similar meaning to 'if'.
Summary

As long as = Only if

• As long as we go somewhere hot.

Suppose + question clause  = How about if ...Note: Use this when making a suggestion.

• Suppose we go to America, will that be hot enough?

Unless = If ... not

• Unless I get the time off work, I won't be able to go.

Providing/provided = IfNote: Provided is more formal than providing but has the same meaning.

On the condition that = If
Note: this is very formal and mostly used in writing.

• On the condition that you pay me extra, I'll work over the holiday.
