Generalizations may also be
uncountable nouns. With uncountable
there are no articles:
Gold is a precious metal.
Rice is a staple food in many
Water is necessary for life
Butter is made from the fat
Venison is the meat of a deer.
Patience is a quality I admire.
Notice that in the examples
above, the first
noun (gold, rice, water, butter,
patience) is uncountable and is used
a generalization. In some of the example
sentences, the second noun is countable
therefore, uses an article: a precious
a staple food, a quality.
