1.
blister
A fluid-filled bubble on the skin caused by friction, heat, or repeated pressure. Commonly occurs on the hands from gripping tools or on the feet from walking or ill-fitting shoes.
2.
callus; corn
A thickened, hardened area of skin that develops from repeated friction or pressure over time.
Usually written in katakana (マメ) or hiragana (まめ) to distinguish from 豆 (bean). The connection is that blisters and calluses resemble small beans in shape.
Common collocations
- マメができる: to get a blister/callus
- マメがつぶれる: a blister bursts
- マメが硬くなる: a callus hardens
- 手のマメ: blister/callus on the hand
Usage
The distinction between blister (fluid-filled) and callus (hardened skin) depends on context. Fresh マメ from short-term friction are blisters; long-term マメ from repeated activity become calluses.
