Compound (linguistics) - Subclasses - Semantic Classification

Semantic Classification

A common semantic classification of compounds yields four types:

• endocentric
• exocentric (also bahuvrihi)
• copulative (also dvandva)
• appositional

An endocentric compound consists of a head, i.e. the categorical part that contains the basic meaning of the whole compound, and modifiers, which restrict this meaning. For example, the English compound doghouse, where house is the head and dog is the modifier, is understood as a house intended for a dog. Endocentric compounds tend to be of the same part of speech (word class) as their head, as in the case of doghouse. (Such compounds were called tatpuruṣa in the Sanskrit tradition.)

Exocentric compounds (called a bahuvrihi compound in the Sanskrit tradition) are hyponyms of some unexpressed semantic head (e.g. a person, a plant, an animal...), and their meaning often cannot be transparently guessed from its constituent parts. For example, the English compound white-collar is neither a kind of collar nor a white thing. In an exocentric compound, the word class is determined lexically, disregarding the class of the constituents. For example, a must-have is not a verb but a noun. The meaning of this type of compound can be glossed as "(one) whose B is A", where B is the second element of the compound and A the first. A bahuvrihi compound is one whose nature is expressed by neither of the words: thus a white-collar person is neither white nor a collar (the collar's colour is a metaphor for socioeconomic status). Other English examples include barefoot and Blackboard.

Copulative compounds are compounds which have two semantic heads.

Appositional compounds refer to lexemes that have two (contrary) attributes which classify the compound.
