Understanding Marginal Modal Verbs: Dare, Need, and Used To
Dare and Need are often referred to as ‘marginal modal verbs’ or ‘semi-modal verbs’. Their unique characteristic lies in their ability to function both as modal verbs and as full lexical verbs.
- As modal verbs (without 'to'):
- He needn’t come.
- He dare not say.
- As full lexical verbs (with 'to' in the infinitive, and requiring an auxiliary verb for negatives/questions):
- He doesn’t need to come.
- He doesn’t dare to say.
Used To is sometimes included in this group, also demonstrating dual usage:
- I used not to go clubbing. (Modal-like, though less common)
- I didn’t use to go clubbing. (Lexical verb usage)
