Type 2 conditional sentences use the past tense after "if" to refer to an unlikely or hypothetical condition and its probable result. The time is now or any time, but the situation is unreal. For example, "If I had time, I would visit her" refers to a possible but currently unreal situation. These sentences are used to talk about something that is not currently possible but could be, or something that could never actually happen. Common contractions of "would" include "wouldn't" and the informal "'d".
