part and depart, job and jobless. Thus, owing to their double or intermediate nature, they will be called lexico-grammatical morphemes.
De-, for-, -er, -less are bound morphemes. English also possesses free lexico-grammatical morphemes, or lexico-grammatical word-morphemes.
Units of the type stand up, give in, find out resemble analytical words in each having the forms of a combination of words and the content of a word. But there is an essential difference between shall give and give in. Shall does not introduce any lexical meaning, while in does. Shall give differs from give grammatically, while give in differs from give lexically. In this respect give in is similar to forgive. Thus, in is an example of a lexico-grammatical word morpheme.
A word has at least one lexical morpheme. It may also have grammatical and lexico-grammatical morphemes. The lexical morpheme is regarded as the root of the word, all the other bound morphemes as affixes: prefixes, suffixes and infixes.
Position is not the only difference between prefixes and suffixes. Suffixes play a much greater role in the grammatical structure of both English and Ukrainian languages. Firstly, they include grammatical morphemes besides lexico-grammatical ones, whereas prefixes are only lexico-grammatical. Secondly, the lexico-grammatical suffixes are more closely connected with grammatical morphemes than prefixes are. Adding a suffix to the root mostly changes the set of grammatical morphemes attached, which is not typical of prefixes.
