I will add that would and could are conditional. I "would" do something if ... When a future action is conditional, would is a better word to use. For example, I WILL eat at seven. Will is definite. Or, I WOULD eat at seven, but I won't be home until eight. Would is conditional here. It is something that could happen in the future, but, in this case, it depends upon whether I will be home at seven or not. Also, I could have begun that first sentence by saying, "I would add..." and that makes sense, too. Would, in this case, is a bit more tentative than will. Will is definite. Would is softer and not as direct. For example: If I say, "I WILLoffer a suggestion," I mean that I intend to do it. If I say, "I WOULD offer a suggestion," I imply that, if it is permissible, then I will do it. Would is a little less direct and dependent upon whether or not I have permission, in this case. I WILL travel by air. It's definite. I've already bought the tickets. I WOULD travel by air if I had the money. I use would because my decision to fly is dependent upon whether or not I can afford it. I hope this helps.

"would" Is used in the present tense, Its saying that if the opportunity arises, you take it. e.g. "I would like to". "Wouldn't" is the negative form of Would. "Will" is future, It means that you will do something for definite. e.g. "I will do that at a later date" "Wont" is the negative form of Will. Hard to explain, Hope this helps you :DD

Even though would and will are related, you really need to know the difference. You cannot ever substitute one for the other. Use "will" when you're sure about something happening. Typically, we use it for future predictions. "Would" is a little more complex. You use it when you can't be so definite, or if you're talking about a prediction (will) made in the past. You can also use "would" to indicate past habits, as well as suggesting an alternate (but unlikely) present possibility. Remember, in both cases these are hypothetical situations, so we're not talking about real actions here.

Will not is presence tense of would not.Would is possitive affirmative while wouldn't is negative and also it is a conjugation of 2 words "would not".
