What are “Compound Words”?
A compound word consists of two or more base words. The meaning of Compound words is often different from the separate base words.
Compound Words and Parts of Speech
Compound words are mostly nouns, adjectives, and verbs.
Kinds of Compound Words
Compound words are of three types:
(A). Closed Compound Words:
Words are joined together. There is no space or hyphen between the words.
Examples: firefly / softball / redhead / keyboard / makeup / notebook
(B). Hyphenated Compound Words:
Words are joined together by a hyphen.
Examples: daughter-in-law / over-the-counter / six-year-old
(C). Open Compound Words:
Words are not joined together. Words are open or separate. In other words, there is a space between the words.
Examples: post office / real estate / full moon / half sister
Some general rules regarding the use of hyphens:-
Compound Adjectives are often hyphenated.
If a compound adjective precedes a noun, they are hyphenated
Examples:
low-paying job [low- paying is a compound adjective; job is a noun]
easy-going celebrity [easy-going is a compound adjective; celebrity is a noun]
Adverbs that end in –ly and compounded with another modifier are generally not hyphenated:
Examples:
deeply held beliefs
genetically modified foods
highly placed sources
quietly organized meeting
