Etymology: "Blain" is an old English word for a painful, swollen blister, and it has been around far longer than most of its readers would guess. It descends from Old English "bleġen," which belonged to a Germanic family of words whose shared sense was swelling up. The Proto-Germanic ancestor may trace back to a much older root meaning "to swell up," though that deeper link is less certain. The family ties are revealing. Dutch "blein" and West Frisian "blein" are close relatives, as is Middle Low German "bleine," all meaning the same thing. Further afield, Norwegian dialect "bleime" and Old Swedish "blēma" describe blisters too, and French "bleime" once named an inflammation of a horse's hoof. The word thus spread across several northern European languages while keeping its focus on a swollen, raised patch of skin.
