[p 86:] For example, determiners
specifywhether a noun is indefi- nite or definite (a boy versus the boy), or the proximity of the person or object to the context (this boy versus that boy). Tense provides the verb with a time
[p 563:] determiner (Det) The syntactic category, also functional category, of words and expres- sions, which when combined with a noun form a noun phrase. Includes the articles the and a , demonstratives such as this and that , quantifiers such as each and every , etc.
determine (v.) "to come to an end," also "to settle, decide" (late 14c.)
I already read this and understand the definitions above. Hereafter, I am using the definition of 'determine' as quoted above, but please tell me if the Root 'determine' in 'determiner' (hereafter DET) means something else or has changed semantically.
I do not comprehend how DET can be interpreted to 'determine'.
p 86 above states that DET
specify (ie: determine) something about the noun, but this appears false because context determines the DET used.
