noun
A fluid-filled bubble on the skin caused by friction, burns, or irritation. Common in everyday conversation.

やけどで水ぶくれができたときは、つぶさないほうがいい。
When you get a blister from a burn, it's better not to pop it.
Rare variant using 脹れ (swelling); mostly seen in older texts.
まめ is a more casual, everyday word for blister, often used for friction blisters on hands or feet. 水ぶくれ is slightly more clinical and emphasizes the fluid-filled nature.
Compound of 水 (water) and 膨れ (swelling, blister). The reading みずぶくれ is a straightforward combination of the kun'yomi readings of the components.
