Is "dare" a modal verb?

[imakedon]

Which of the two below is a correct English phrase please (Oh, no, not “neither”, huh?):
(a) I would not dare to unscrew…
OR
(b) I would dare not to unscrew…
(“Dare” specificity is meant here).
Thanks.

In the right context, you could use both. The first is more likely.

Neither of these sentences does much to demonstrate whether dare can be a modal verb. Dare can behave like a modal verb sometimes- when we say I daren't tell them, it is. It is sometimes classified as a semi-modal, like need, which means that it can behave like a modal or like an ordinary verb.

In neither of those sentences does DARE function as a modal verb.
