· Abstract nouns are both
count and non-count ones. The rules of articles with count abstract
nouns/idea, thought, method, dream, invitation,
etc/ are the same as those of the use of articles before
concrete count nouns ,for example: I have an idea for a new book.
· Abstract non-count nouns /love, hatred,
education, importance, knowledge, power, peace , possibility,
etc./ are used without an article in their most general meaning.
For example: But then, of course ,there was love.
· If nouns of the second group denote concrete instances or special
aspects of the given notion they become count nouns and are used with
both articles. The use of the indefinite article is typical of nouns
with a descriptive attribute .For example: She lived a long life and
died a natural death. Drinking was the death of him
The abstract nouns advice, information
,fun, luck, weather are never used with the indefinite
article .For example The play at the theatre was very poor fun. Such
weather had a nervous effect on him
