English contains many compound nouns, which combine two words to create a single concept.
Examples include:
- Classroom
- Teammate
- Schoolmate
- Roommate
- Workmate
- Classmate
Over time, many compound nouns evolve from two separate words into one accepted word.
Evolution of Compound Words
Many English words follow this pattern:
- Open compound (two words)
- Hyphenated compound
- Closed compound (one word)
For example:
- Web site → Website
- Data base → Database
- School mate → Schoolmate
- Class mate → Classmate
Today, classmate is firmly established as a closed compound noun.
