The adjective. Types of adj. Degrees of comparison

Semantic classification of adverbs.
We can distinguish two large groups of adverbs:
1) non-spatial and
2) spatial.
To non-spatial adverbs belong:
1) viewpoint adverbs (e.g. Looked at politically, it was not an easy problem);
2) focusing adverbs (e.g. He is doing it purely and simply for your benefit);
3) intensifying adverbs (e.g. It's simply a question of hard work);
4) process adverbs (e.g. They treated him badly);
5) subjective adverbs (e.g. Bitterly, he buried his children);
6) adverbs of cause and consequence (e.g. We have a growing population and therefore we need more food).
To spatial adverbs belong:
1)place adverbs (e.g. They are not there; He threw his manuscript aside);
2) time adverbs (e.g. He arrived last night; He washes his car every Sunday).
Similar to adjectives, adverbs can be gradable and non-gradable. Gradable adverbs are adverbs which are capable of expressing the intensivity of the process, e.g. loudly - more loudly -the most loudly. The number of non-gradables is much greater among adverbs than among adjectives.

The adv. is a PS characterized by the following features:

1. 
   the lex.-gram. mean. of “qualitative, quantative or circumstantial characteristics of actions, states or qualities:
   
2.
