Expletive
constructions: Standard English has a number of what we call
expletive constructions. These occur when we use “place-holder” or empty words
in order for our grammar to make sense to us.
Like infinitives, both participles and gerunds are nonfinite
phrases. And, like infinitives, they are words that derive from – come from –
verbs, and yet do not function as verbs.
Nonfinite phrases are like dependent clauses in that they can
act as nouns, adjectives, and adverbs. They are unlike dependent clauses in
that they contain nonfinite verb forms rather than finite verbs.
