'Word' and 'Sentence' - 2 sides of the same coin!

Take a sentence - John gave a book to Jack. This is made up of words.

The meaning of any word in the sentence is a combination of the meanings of some other words. So why isnt there a word for this given combination of words - the original sentence?

Well, there is something like a ‘General meaning’ (given in dictionaries; of words) and ‘Instantial meaning’ which is of specific “story-sentences” (which are combinations of words). General meaning is the generalization of an instantial-meaning-sentence. 

Relationship between a word and a sentence/string - 

Given Word -> converts to general meaning string -> Case of which is -> Instantial Meaning string -> Generalize -> converts to word (in many cases)

Thus 'word' and 'string/sentence' are 2 sides of the same coin - the conversion operator being - GENERALIZE/INSTANTIATE!

E.g. - 

Give -> transfer the possession of something to someone -> John transferred the possession of a ball to Jack -> someone transferred the possession of something to someone -> gave
