pluralIn mathematics, a complex number was a number of the form a + ik (a and b are both real numbers). i was called the imaginary unit, satisfying i2 =-1. The complex number was usually written as z = a + ik, a was the real part, ik was the imaginary part. The set of all complex numbers was called the complex number set or complex number field, often represented by C.
In English, there were many rules for plurals:
1. Under normal circumstances, it was an S.
2. If a word ends in s, x, or d, then add es when it becomes plurals, for example, fox-foxes, dish-dishes, watch-watches, bus-buses.
3. If the word ends with f or fe, change the word to v and add es, for example, knife-knives.
"Choose" was equally exciting. Everyone was welcome to read it!
What is the plural of story?Well, in English, when we talk about more than one'story', we use the word'stories'. It's a common rule for many nouns that end with 'y' preceded by a consonant. We change the 'y' to 'i' and add 'es'. So, for example, we say 'I have read two stories this week'.
Can a novel be plural?Yes, a novel can be made plural. Just like with most nouns, when you have more than one, you add an 's' to make it 'novels'. For instance, 'I have read several novels this month.' shows the plural usage.
