"What's the plural of knife?"

Which is Correct: Knifes or Knives?

The correct plural form of the word "knife" is "knives." While "knifes" may appear to follow the regular pluralization pattern, it is not the accepted form in standard English usage.

English nouns ending in -f and -fe often form their plural by replacing the -f with -ves.

Is Knife a Countable or Uncountable Noun?

The word "knife" is considered a countable noun. Countable nouns refer to objects or entities that can be counted as separate units or individuals. Each knife is considered a distinct item, and its plural form "knives" reflects this countability.

You can use numerical quantifiers such as "one knife," "two knives," "three knives," and so on to specify the quantity of knives.

Countable nouns have both singular and plural forms, and they can be used with articles like "a" or "an" for singular nouns and "the" for plural nouns. For example, you would say "a knife" when referring to one knife and "the knives" when referring to multiple knives.

Collective Noun for a Group of Knives

In English, there isn't a widely recognized collective noun specifically dedicated to a group of knives. However, you can use the term "set" to refer to a collection of knives that are part of a specific set or arrangement.

For example, if you have a group of knives that come together as a unit for a specific purpose, you can refer to them as a "set of knives."
