*Flys or Flies | Correct Spelling & Examples

Flys is a misspelling of flies, a common verb and noun. Flys is always incorrect, and flies is always correct.

Flies or flys

Flies is the simple present tense of the verb “fly,” meaning “to move through the air using wings.” Flies is also the plural form of the noun “fly,” a common insect.

Flys is not a word. Regardless of whether you use the noun or verb, the word is always flies.

For example, if choosing between “flies by” or “flys by,” the correct spelling is “flies by” (e.g., “That bird flies by my window every day”). Likewise, if choosing from “flys a plane” or “flies a plane”, the correct option is “flies a plane” (e.g., “My aunt flies a plane as a hobby”).

The common mistake of flys probably comes from people adding an “s” to the verb “fly,” as this is how you usually form the third-person singular in the present tense in English.

However, when the base form ends in “consonant + y,” you must remove the “y” and add “ies.” The same rule applies when forming the plural of a noun that ends in “consonant + y.”

Time flies or time flys

“Fly” is used in idioms (e.g., “as the crow flies” and “fly off the handle”) and phrasal verbs (e.g., “fly into” and “fly by”).

One example is “time flies when you’re having fun,” which means that time seems to go faster when you’re enjoying yourself. When using this idiom or a variation of it, the correct spelling is always time flies and never time flys.
