Pronunciation: [flˈa͡ɪ blˈɪstə] (IPA) 
The word "fly blister" is spelled with an "i" in "fly" and a "y" in "blister". This combination of letters creates a unique sound in IPA phonetic transcription: /flaɪ/ /ˈblɪstər/. The "y" in "blister" represents the vowel sound, /ɪ/ as in "sit". Meanwhile, the "i" in "fly" represents the diphthong, /aɪ/ as in "eye". These different vowels sounds are blended together to create the distinct pronunciation of "fly blister".
A fly blister refers to a small, fluid-filled swelling or raised bump that develops on the skin as a result of an insect bite or sting, specifically caused by certain species of flies. When flies bite or sting a human, they inject a substance into the skin that irritates it, leading to the formation of fly blisters. These blisters typically appear as tiny, red or pink welts, often accompanied by intense itching or a burning sensation in the affected area.
Fly blisters can be caused by various types of flies such as horse flies, deer flies, or black flies. Although relatively small in size, fly blisters can be quite painful and may take a few days to heal completely. In some cases, the itchy sensation caused by these blisters can become overwhelming and cause distress.
Treatment for fly blisters often involves applying over-the-counter anti-itch creams or lotions to alleviate the discomfort and reduce swelling. Keeping the area clean and dry is crucial to avoid potential infections. If the fly blister becomes infected or shows signs of worsening, it is advisable to seek medical attention for proper diagnosis and management.
Prevention of fly blisters can be achieved by taking measures to avoid contact with biting flies, such as wearing protective clothing, using insect repellents, and avoiding known fly-infested areas.

The term "fly blister" is a compound word composed of two parts: "fly" and "blister".
"Fly" originated from Middle English "flien" or "fleȝen", which derived from Old English "fleogan". This word is related to the Old Norse "fluga", meaning "fly" or "insect". The Old English word eventually evolved into the modern English term "fly", referring to various types of winged insects.
On the other hand, "blister" originated from the Middle English word "blister" or "blustere", which can be traced back to Old English "blǣst", meaning "bladder" or "swelling". The word "blister" refers to a swelling or bubble-like protrusion on the skin due to friction, heat, or irritation.
