What are Gerunds, infinitives, and participles?
A gerund is a word with a "ing" ending that functions as a noun. A verb that has been given the "-ing" suffix has been altered so that the entire word now functions as a noun.
A verb's basic form gains the word "to" to produce an infinitive, which can then be used as a verbal noun, adjective, or adverb.
Depending on the root word, a participle is a verb that serves as an adjective and ends in one of the following suffixes: "-ing," "-ed," "-en," "-d," "-t," "-n," or "-ne."
When a participle and one or more nouns or pronouns are united, they form a participial phrase, which is a group of words.
