    • Simple Modals• Have single forms Historical Present Tense Past Tense Can Could May Might Must ------ Shall Should Will Would
    • Periphrastic Modals• Formed with the verbs be and have• ‘Phrase-like’ instead of single word forms Be able to Be allowed to Have (got) to Be supposed to Be going to Ought to
    • • One kind of auxiliary verb (like ‘be’ and ‘have’)• Precedes the main verb in the predicate – Directly She might run in the race. – Before auxiliary verbs She might be running.• Does not take the present tense –s or the past tense –ed inflections – *He shoulds eat the candy. – *He shoulded ate the candy.• Can contract with ‘not’ – He shouldn’t talk to her. – *He worksn’t with her.
    • Modal MeaningsEpistemic Root• What is known by • What is socially the speaker/writer determined• Fact-based • Authority• ‘necessary that’ relationship (must) • ‘necessary for’ (must)• ‘possible that’ (may) • ‘possible for’ (may)

    • Social Function of Modals• Making requests – Can/could you help me with my homework? • Yes, I can./Yes, I could. – May/might I leave the room now? • Yes, you may./Yes, you might. – Present tense form is more direct, historical past tense form is used to soften a request (make it more polite)• Request modals change meaning when “not” is contracted vs. when it precedes the main verb – Won’t you please get into the pool? (Please get in.) – Will you please not get into the pool? (Please do not)
    • CAN/COULD Ability Permission (root) Possibility (epistemic)• Extended Meanings – Speculation/Regret – Disbelief – Suggestion/Implied Criticism

    • Problems ESL/EFL Students May HaveDebes nadar.*You should to swim.I have a dog.I have sold the dog.Adding inflections like main verbs
    • Teaching Ideas• Examine expository written discourse (magazine articles) and note modal verbs and possible meanings in context• Use continuum (probably, possibly, not likely) to create sentences from prompts – Rain today (possibly) It may rain today.• Create directions for a game• Describe what you could/couldn’t do as a child vs. what you can/can’t do as an adult• Change abrupt sentences into more polite ones using modals – You’re not very busy. You can help me. – You don’t seem very busy. Could you help me?
