Some English nouns such as family, room, mouth, ear, etc. seem to be only countable nouns. However, they can express abstract senses in certain collocations:
to have too much family(= too heavy family burden)
to have too much winter(= a too long spell of cold weather)
to have too much mouth(= to talk too much)
to have too little ear(= to be not inclined to listen to others)
to have room for(= to have a need for)
to feel the patriot rise(= to feel the patriotic feelings rise)
Some English nouns (fool, man, coward, coquette, scholar, poet, politician, sportsman, etc.) that are usually countable can become uncountable when referring to people’s features:
to be fool enough (= to be foolish enough);
more of a fool (= more foolish);
less of a fool (= less foolish);
as much of a fool as (= as foolish as);
too much of a fool (= too foolish);
He was enough of a man to tell the truth.
