A compound noun is that noun that consists of two or more words which are combined to form a single unit. It can be written as a word (closed or solid), hyphenated, or written as two words (open or spaced).
This type of noun is formed by combining two nouns or different parts of speech. Some of them are: noun+noun, verb+noun, adjective+noun, preposition+noun, verb+preposition.

Most compound nouns have plural endings to convert them to plural words, e.g. hotplates, websites, swimming pools, dressing tables.
However, compound nouns such as brother-in-law and sister-in-law change to brothers-in-law and sisters-in-law respectively.
Also, afterlife is usually used in the singular form, and others such as offspring and aircraft do not change—their plural forms are same as singular.
The stress placement that makes us pronounce a part of a word louder than the rest is usually on the first part of compound nouns, e.g. AFterlife, WEBsite, HOTplate, etc.
However, words such as South Africa, Prime Minister, Mount Everest are pronounced with stress on the second word as South AFrica, Prime MINister, Mount EVerest respectively.
In conclusion, good dictionaries tell us how to write, pluralise and pronounce compound nouns.
