I've heard somewhere that there's a slight difference between "as though" and "as if" as to when they are used. Can you explain this?

We use "as if" and "as though" to make comparisons and to talk about an imaginary situation or a situation that may not be true but is likely or possible. They have a similar meaning. Both are commonly used after verbs like "feel" and "look". "As if" is the more commonly used expression, and has its own distinct use to express disbelief. Ex: She moved her hands as if she was drowning. Ex: It looks as though we won't be able to finish our project on time. Ex: What do you mean you don't want to come to the party. As if! (colloquial use to express disbelief, cannot be replaced with "as though")
