Compound tenses are made up of auxiliary verbs (or helping verbs) combined with other verb forms. The perfect, past perfect (also known as pluperfect), progressive, and (in some cases) future are forms traditionally regarded as compound tenses in English.

For example, “My son and heir will rule this kingdom.” In this sentence, “son” and “heir” refer to the same person. Generally speaking, however, compound subjects will be treated as plural and take a plural verb: Dolphins and elephants are highly intelligent creatures.

A compound adjective is formed when two or more adjectives are joined together to modify the same noun. These terms should be hyphenated to avoid confusion or ambiguity. For example: Diana submitted a 6-page document. She adopted a two-year-old cat.

Compound adjectives can be formed as follows:

• Adverb-past participle / noun + ed. a well-known writer.
• Adjective-present participle (verb + ing) a good-looking boy.
• Noun-past participle. a tongue-tied boy.
• Adjective-past participle / noun + ed. a short-sighted man.
• Noun- adjective.
• Adjective- noun.
• Noun-noun.

A compound adjective is an adjective that contains two or more words. In general we put a hyphen between two or more words (before a noun) when we want them to act as a single idea (adjective) that describes something. I live in an English-speaking country.

In graph theory, a cycle in a graph is a non-empty trail in which the only repeated vertices are the first and last vertices. A directed cycle in a directed graph is a non-empty directed trail in which the only repeated vertices are the first and last vertices. A graph without cycles is called an acyclic graph.
