Sorry Kiwi I know you did not invent the term Modal Verbs but I would just like to say that Modals are not verbs.
Starting with the premise that they are causes confusion for learners of English.
Modals cannot be conjugated. They do not have any tenses.
Could for example is not the past of can.
I can do it now = present ability.
I could do it now = present possibility.
I could do it yesterday = past ability.
I could do it tomorrow - future possibility.
Why Modals came to be called "Modal Verbs" I don't understand.
For me they are closer to adverbs because they are most of the time used to modify verbs.
Yes, Sir Ian is correct. They are called "verbs" at times, but aren't really because they cannot be used alone.
Modal "verbs" are called auxiliary verbs, helping verbs and model auxiliaries. Model "verbs" are not complete verbs, and they can only be used with a verb.
For anyone who would like to practice what they learnt or test their knowledge here's a self checking exercise on modal 'auxilliaries' (smiley)
