Question

find out the word which is not compound - water-logged foot-ball self-esteem multinationational​

Answer 1

Multinationational ​is not a compound word.

Water-logged, football, and self-esteem are compound words.

Compound words are the words which are made up of two or more words which are small to form a new word which has its own meaning. There are three types of compound words, closed compound words, open compound words, and hyphenated compound words.

Answer 2

Compound words are formed when two or more words are joined to form a new word and a new meaning accordingly.

They can be open, closed or hyphenated. From the words given in the question, the word that is not a compound is waterlogged.

This is because the words water and logged cannot express meaning in a stand alone manner.

The other words when separated do make meaning separately.
