Study Notes

Modals

Modals are auxiliary verbs used to express different meanings, such as necessity, ability, permission, or obligation. They often appear before the main verb in a sentence and change its meaning, functioning more like adverbs than regular verbs. In English, four common modals are "can", "could", "might," and "must".

Can

The modal "can" is used to indicate possibility, potential, or capability. It shows that something may be done or is possible under certain conditions:

"I can play tennis." (indicating physical ability)
"She can't drive a car." (showing lack of ability)
"Can you help me with this task?" (asking permission)

Could

Similar to "can," "could" also indicates ability, but it suggests less determination or a hypothetical situation:

"He couldn't finish his work because he was sick." (suggesting impossibility due to illness)
"Could you please pass the salt?" (polite request)
"What would happen if we could control our dreams?" (hypothesizing a scenario)

Might

Unlike "can" and "could," which suggest concrete possibilities or abilities, "might" is used to convey uncertainty or possibility without definiteness:

"Might is right," expresses doubt about what is considered right; it does not imply that might actually means right.
"It might rain today," implies there is some likelihood of rain but not certainty.

Must

"Must" is the most forceful of all the modals. It represents absolute necessity, obligation, or requirement:

"You must pay your taxes," emphasizes legal compulsion.
"We must leave now," conveys urgency.
When followed by a comma, "must" changes to a strong suggestion, not a command or requirement: "You must, commas, have a plan B."

In summary, modals provide a richer set of meanings than simple tense indicators, allowing us to express various shades of ability, obligation, permission, and potential within sentences. An awareness of these nuances can greatly enhance communication.
