How Do You Spell Flies? The Comparison and FAQs

Have you ever found yourself in a situation where you need to spell the word “flies” correctly, but you’re not sure which letter to use – i.e., is it spelled “f-l-i-e-s” or “f-l-y-s”? If yes, worry no more because in this article, we will explain how to spell flies correctly, compare it with similar words, and answer some frequently asked questions.

How to Spell Flies Correctly

The correct spelling of the word we’re discussing is F-L-I-E-S, which is a plural form of fly. A fly, in this context, refers to “any of numerous two-winged insects of the order Diptera, especially of the family Muscidae, as the common housefly.” Therefore, when you talk about multiple flies, you use the plural form “flies.”

It’s important to note that “flies” is not the only form of this word that exists. There are other variations, such as:

– Fly: This is the singular form of the word. It refers to a single insect that belongs to the fly family. Example: There’s a fly on the wall.
– Flyer: This one is a noun that means “a person or thing that flies or moves rapidly through the air.” Example: The plane is a fast flyer.
– Flys: Although some people use this spelling, it’s incorrect. There’s no plural form of “flys” – it doesn’t exist in the English language.

Comparison with Similar Words

Now that we’ve established the correct spelling of flies, let’s compare it with some similar words that you might confuse with it.

Flies vs. Flys

We’ve already touched on this point a bit, but it’s important to emphasize that “flys” is not a correct spelling of the plural form of “fly.” If you write “flys,” you’ll be making a spelling mistake that might confuse your reader. Therefore, when referring to multiple insects that belong to the fly family, use “flies.”

Flies vs. Flied

“Flied” is a past tense form of the verb “fly.” It’s what you would use to talk about an object that was hit in such a way that it flew through the air. For example, “The baseball was hit so hard that it flied over the fence.” The difference between “flies” and “flied” is the tense. While “flies” refers to present or future events where there are multiple insects, “flied” refers to past events where something flew as a result of a hit.

Flies vs. Fluoresce

Fluoresce, on the other hand, means to emit light (usually of a particular color) as a result of being excited by radiation or another substance. For example, “The fluorescent lights in the room make the colors appear brighter.” It has nothing to do with insects, let alone the plural form of “fly.” Therefore, if you’re writing about lights that emit light, use “fluoresce,” and if you’re writing about insects, use “flies.”

Flies vs. Fleece

Finally, “fleece” refers to a fabric made from sheep’s wool, or a verb that means to swindle or cheat someone out of money. For example, “He was fleeced by a con artist.” It has nothing to do with insects either. Therefore, use “flies” when referring to insects and “fleece” when talking about wool or scams.


Q: Is “flies” only used for houseflies, or can it refer to other insects as well?
A: “Flies” is a word that’s used to describe multiple two-winged insects of the order Diptera, including but not limited to houseflies. Therefore, it can refer to other species of flies as well, such as fruit flies, horseflies, blowflies, etc.

Q: Can “flies” be used as a verb?
A: Yes, “flies” can be used as a verb, depending on the context. For example, “The bird flies in the sky,” where “flies” means “to move through the air with wings.”

Q: Is it necessary to add an apostrophe after the “y” when spelling “flies”?
A: No, it’s not necessary to add an apostrophe after the “y” when spelling “flies.” The apostrophe is only used when indicating possession or contraction, neither of which applies to this case.


In summary, the correct spelling of the plural form of “fly” is F-L-I-E-S. It refers to multiple two-winged insects of the order Diptera, including species such as houseflies, fruit flies, etc. While there are other variations of this word, such as fly, flyer, and flied, “flys” is not a correct spelling. Also, “flies” cannot be interchanged with “fluoresce,” “fleece,” or any other word that has a different meaning. Therefore, always use “flies” when referring to multiple insects of the fly family.
