Flys and Flies are two words that sound the same but have different meanings. Flys is a verb meaning to move through the air, while Flies is a noun referring to an insect of the family Diptera. The word Flys can be used as either singular or plural, while Flies should only be used in its plural form (e.g., “The flyswere buzzing around”).
Therefore when discussing insects, it would be correct to say “Flies are pesky creatures” instead of saying “Flys are pesky creatures”. When referring to movement through the air, however, one could say “She flew across the room” or “They flew away”; both sentences use Flys correctly as a verb in the past tense form.
When it comes to grammar and usage, there is often confusion between the words “flys” and “flies”. While both terms may refer to an insect of the order Diptera, they are not interchangeable. The word “flys” is a form of a verb meaning to move through the air, while “flies” refers specifically to insects.
Thus, if one were referring to any type of flying creature other than an insect (e.g., a bird), they would correctly use the term “fly” rather than “flies”.
