Nouns mention people, places, things or ideas. Most nouns are countable, and come in a singular or plural noun form. By and large, most nouns in English add “es” or “s” to denote a plural. These are called “regular nouns”.
Irregular nouns become plural by some other inflection, or they may simply remain as is. These nouns are harder to learn, but we have the answers to all the common questions on proper noun forms; like, “what’s the plural of sheep?”, “is fish plural or singular?”, “is ox plural oxes, or oxen?” To all of your questions on plural nouns, we have the answers. Also, no, meese is not the plural of moose; it’s just moose.
The plural of child (which is singular), is children (plural noun). Like man and woman, children is an irregular plural noun in English since it doesn’t end in -s/-es.
Curriculum is a Latin noun, and has two accepted plural noun forms: curriculums and curricula. Both are correct; though curricula is the original Latin pl. n. form.
The plural of half (rhymes with calf) is halves. Half is a sibilant, and like calf, loaf, and wolf, each uses -ves to denote a plural noun form.
Phenomenon is singular. Phenomena is plural.
Dwarfs is the more common plural. Dwarves refers to mythical creatures, and was popularized by JRR Tolkien.
Is there an elf on your shelf? If there were more than one, there are elves on your shelf (or shelves, if you have more than one shelf, too).
The plural of life is lives, as in The Days of Our Lives. ‘Life’ is a singular noun.
The plural of wharf is wharfs or wharves. Singular nouns that end in f/fe normally take on ves as a plural.
Axis plural is axes (not to be mistaken for the woodsman’s tool, albeit spelled the same.)
The plural of hypothesis is hypotheses. Hypothesis is the singular noun form.
