Two branches of grammar – morphology, syntax

There are two branches of grammar: morphology and syntax. Morphology treats of the forms of words; syntax treats of phrases and sentences. The problem of distinguishing between a word and a phrase: word is a nominative unit of language, it enters the lexicon of language as its elementary component (indivisible into smaller segments as regards its nominative function, the function to name things, properties, actions, etc). Phrases consist of separate words, though analytical forms of words (has been found), which historically were phrases, lost syntactical connections between their parts. There can also be a word between these parts (has often been found), which is one of the cases of overlapping syntax and morphology. Another case is analytical word – take off, put on. Thus, the polar approach to the definition of a word is “minimal unit of a language possessing the positional independence in the sentence. It is the smallest discrete unit, the smallest unit capable of syntactic functioning and the largest unit of morphology”.
