Flies Vs Flys

Flies vs Flys: Understanding the Difference

Flies and flys are two words that denote different things. While one refers to the insect that is known for its buzzing and pesky nature, the other refers to a type of baseball catch. Though the two words sound similar and have only a letter’s difference in their spelling, their meanings are vastly different. In this article, we will explore the difference between flies and flys and how to use these words correctly in a sentence.


The word fly is commonly used to describe the tiny, winged insects that belong to the Diptera order. These insects are usually about 1/8 to 1/4 inch long and have a pair of wings on either side of their body. They are known for their buzzing and pesky nature, as they are commonly found around rotten food and garbage. While some species of flies are harmless, others can transmit diseases such as salmonella, cholera, and tuberculosis.

Flies can be found in various types of environments, including homes, outdoor spaces, and agricultural areas. They thrive in warm, moist conditions and can lay hundreds of eggs in just a few days.


The word flys is often used to describe a type of catch in baseball. It refers to a ball that is hit high into the air and caught by one of the outfield players. The term is derived from the fact that the ball seems to “fly” through the air, and the outfielder must use their hand-eye coordination to catch it.

The use of the word “flys” in this context is relatively uncommon. Most commonly, this type of catch is simply referred to as a “fly ball” or “pop fly.”

Comparing Flies vs Flys

The difference between flies and flys is quite clear. While one refers to the small, pesky insects that can be found in various environments, the other refers to a type of catch in baseball. Additionally, the words are pronounced differently, with ‘flies’ pronounced with a long i sound, while ’flys’ has a short i sound.

One may wonder if the word flys with an “i” is a typo of the actual word fly with a “y”. However, this is not the case. Flys with an “i” is a legitimate word, although it is used less frequently than the word “flies” as plural for fly.


1. Can the word “fly” be used as a verb?

Yes, the word “fly” can be used as both a noun and a verb. As a verb, it means to move through the air with wings or to travel by air or in an aircraft.

2. What is the difference between a fly and a mosquito?

A fly and a mosquito are both insects, but they belong to different orders. Flies belong to the Diptera order, while mosquitoes belong to the Culicidae family. Flies are typically smaller and have two wings, while mosquitoes have thinner bodies and a distinctive long proboscis for biting.

3. Are flies dangerous?

Certain species of flies, such as the tsetse fly and the house fly, are known to transmit diseases. House flies can transmit numerous diseases, including salmonella, cholera, and tuberculosis. Tsetse flies transmit a parasite that causes African sleeping sickness.


In conclusion, flies and flys have vastly different meanings despite being a letter apart in their spelling. “Flies” refers to the pesky insects commonly found around garbage and rotten food. On the other hand, “flys” refers to a type of catch in baseball, where a ball is hit high into the air and the outfielder attempts to catch it before it lands. It is essential to use these words appropriately in order to avoid confusion and to communicate effectively.
