 An endocentric compound refers to the combination of two or more words or phrases in which the grammatical head of the compound expresses its main meaning. Examples include information fatigue, arm chair and bank note. Information fatigue is a type of fatigue, arm chair is a type of chair and bank note is a type of note. Heads can be nouns resulting in nominal compounds, adjectives resulting in adjectival compounds or verbs resulting in verbal compounds. While the head defines the meaning of an endocentric compound, the modifier narrows that meaning, making the compound a hyponym of the head. In English, endocentric compounds are typically right-headed. However, they are also left-headed endocentric compounds, as for example, mother-in-law or commander-in-chief.
