Is there a term for words that are built by combining other ordinary English words together?
For example:
- catfish = cat + fish
- firetruck = fire + truck
- farmhouse = farm + house
- birdcage = bird + cage
They’re called compound words.
According to Wikipedia:
Compounding occurs when two or more words or signs are joined to make one longer word or sign. The meaning of the compound may be similar to or different from the meaning of its components in isolation.
From Cambridge Dictionary:
Many compound nouns are written as one word, but some are written with hyphens or spaces. In modern English, hyphens are less common than they were in the past.
Examples of one word:
- bathroom sheepdog windscreen
Examples of hyphens:
- check-in fire-fighter son-in-law
Examples of spaces:
- bottle opener New Year’s Day Prime Minister
