In linguistics, noun phrases have grammatical number. Singular is one kind of grammatical number. A singular noun phrase usually refers to something that you would count as one only (e.g., "one time", "a glass", "the sun", "my mother", "Jennifer"). Noun phrases that cannot be counted are also singular in English (e.g., "water", "the meat", "some space", etc.). In contrast, plural noun phrases are counted as more or less than one (e.g., "no bananas", "0.5 liters", "1.2 grams", "two times", "three fish", "20 mothers").
