- English auxiliaries differ from verbs in that they show the following properties, the NICE properties:
Negation:
A finite auxiliary precedes the negation particle not to negate a sentence.
- Pat will not walk home.
- *Pat walked not home.
Inversion:
A finite auxiliary stands at the beginning of a sentence in yes/no-questions.
- Will Pat walk home?
- *Walked Pat home?
Contraction:
There is an idiosyncratic contraction form of the auxiliary and the negation particle. won't, can't
Ellipsis:
An auxiliary can occur in VP ellipsis, i.e. at the end of a sentence when a VP is missing.
- Pat should walk home and Mary might, too.
- *Pat walked home and Mary walked, too.
General properties of the modal auxiliaries: no inflection for 3rd singular only a finite form Problematic cases: The verbs be and have have the properties of both verbs and auxiliaries. The support verb do is similar to be and have, but only has a finite form. Infinitival to shows many properties of auxiliaries, and is considered an auxiliary in many theories of grammar.
