A verbal is a verb form that does not function as the verb of a clause. Verbals include
present participles (the -ing form of the verb)
past participles (the verb form usually ending in -d, -ed, -n, -en, or -t)
gerunds (present participles used as nouns)
infinitives (the word to plus the base form of the verb)
Verbals can take objects, complements, and modifiers to form verbal phrases. These phrases are classified as participial, gerund, and infinitive.
Participial phrases
Participial phrases always function as adjectives. Their verbals are either present participles, always ending in -ing, or past participles, frequently ending in -d, -ed, -n, -en, or -t (many irregular verbs have irregular past participles).
Participial phrases frequently appear immediately following the noun or pronoun they modify.
Unlike other adjectival word groups, however, which must always follow the noun or pronoun they modify, participial phrases are often movable. They can precede the word they modify.
They may also appear at some distance from the word they modify.
Gerund phrases
Gerund phrases are built around present participles (verb forms ending in -ing), and they always function as nouns: usually as subjects, subject complements, direct objects, or objects of the preposition.
Infinitive phrases
Infinitive phrases, usually constructed around to plus the base form of the verb (to call, to drink), can function as adjectives, adverbs, or nouns. When functioning as a noun, an infinitive phrase may appear in almost any spot in a sentence, usually as a subject, subject complement, or direct object.
NOTE:In some constructions, the infinitive is unmarked; in other words, the to does not appear: No one can make you [to] feel inferior without your consent.
