Final answer:
A hyphen is used to join two or more verbs that form a single verb.
Step-by-step explanation:
True, A hyphen is used to join two or more words serving as a single modifier before a noun. This is often seen when two or more verbs combine to form a compound verb.
For example, in the sentence 'She is a well-known singer-songwriter,' the hyphen is used to connect the two verbs 'sing' and 'write' to form the compound verb 'singer-songwriter.' Without the hyphen, the sentence would be grammatically incorrect.
