While teaching my classes I had the same argument but then I came to the idea of the usage for old habits or something similar:
-I used to play Basketball
This is an example of the "used to" structure to talk about old habits, we can, here, use the would:
-We would play basketball every Sunday afternoon.
You also use would in questions as in:
-Why would you do that?
And as in polite petitions:
-I would like you not to do that
If I remember correctly, can is a modal verb. A modal verb is a verb that changes the meaning of other verbs. Take this phrase for example: "I play" means exactly what it says, you're playing and having fun. Stick "Can" in, and the meaning changes. "I can play" means that, whilst you may not be playing, you have the ability to do so. There are other modal verbs in English, such as must, would, might, should etc. Modal verbs are very important in English and they are irregular when compared to other verbs. (see the website at the related link) Can is also a noun. "Please hand me that can of soup."
Auxiliary verbs are helping verbs .Modal Auxiliaries are used before ordinary verbs to express meanings. Some of the modal auxiliaries are would ,shall ,shouuld ,can ,could , may ,might,etc.
"Could", "would", and "should" are all auxiliary verbs, used to form special tenses in combination with other verbs. In modern English, this is the only idiomatic use of "could", "should" or "would", although in earlier centuries "would" was used as a synonym for "wish" or "want". Note that "could" is a past tense for which the present tense is "can", but the other two of these auxiliary verbs do not change for tense.
"Could" is part of a special group of verbs known as modal auxiliary verbs. Some other modal verbs are may/might, will/would, shall/should.
Will, would, shall, should, can, could, may, might, must are the Modal verbs.
The modal is the most common number. For example, if you had, 2,1,3, 4,4,3,2,2,1, the modal would be 2, since there is 3 2s
an auxiliary verb that expresses necessity or possibility. English modal verbs include must, shall, will, should, would, can, could, may, and might.
Common sense should tell you that common sense is not a word, it is a phrase made from two words.
No, "would" is not a preposition. It is a modal verb used to indicate possibility, willingness, or polite requests in English.
Common sense would be associated with the pre-frontal lobes.
Examples of an appropriate modal verbs are:he can not do it;he could not do it;he must not do it;he should not do it;he will not do it;he would not do it.
