Theme: the adjective and the adverb

adjectives adverbs:
hard nut to work hard
late hour come late
fast train to run fast
"Probably, evidently, possibly" are not adverbs, but modal words. But the adjectives and adverbs are different parts of speech as B.S.Khaimovich and B.I. Rogovskaya point out, because they perform different syntactical functions have different combinability and different form and meaning.
The grammatical category of degree of comparison of adverbs.
1.Degree of comparison of adverbs are formed in 3 ways:
1) synthetic: fast-faster, fastest: He works faster late-later, latest He came eater
2) syntactical (analytical):quickly-more quickly, most quickly
3) suppletive: well-better-best, badly-worse-worst
B.S.Khaimovich and B.I.Rogovskaya distinguish two kinds of adverbs as to the category of the degree of comparison.
1)comparables: soon-sooner-soonest 2) non-comparables: yesterday, always, upstairs etc.
There are certain limits of the adverb class: We often come across such language phenomena as: come in, go out, stand up, put down, being up, etc. Especially in "put up (with) something" and "bring up" there are not any meanings of neither ''bring'' or ''up''-it meaning to educate. The above mentioned group of words have been treated by different scholars in different ways. First fall, it is linked with the argument as to its being a phrase or a word. If it is a phrase, what part of speech are the second elements ''up', in, down, on, off”?
Some linguists think that they are adverbs. H. Palmer treats them(up, on, off, down” as “preposition- like-adverbs”. So does A.I.Smirnitsky. A.Anitchkov thinks that they are “adverbial postpositions” prof. N.Amosova thinks that ''up'' is a special kind of form words, called "postpositives". Zhluktenko says that it is a word, second part being a morpheme called “postpositive prefixes” like “upbringing”(bring up),”income(come in)”, “up keep)keep up)”. Prof. Ilyish thinks that they ''up, down, away'' are postpositions, so they are special class of parts of speech. So B.A. Ilyish thinks that they are phrazeological units consisting of the verbs and adverbs and have to be treated in lexicology while learning a chapter devoted to phraseology. But we think that they are prepositions used in the needed cases in postposition(the proof of that is that when they are taken in close combination with the following word. They prove to be prepositions- HGM).
Problem of substantivization of adverbs (( in cases they behave like nouns do( for example: Everywhere is your home. Nowhere is not home, Elsewhere is not a good option, etc.) it is a new aspect of adverb theory for the first time noticed by us).
