Etymology
Origin of ulcerate
1375–1425; late Middle English < Latin ulcerātus (past participle of ulcerāre to make sore), equivalent to ulcer- ( see ulcer) + -ātus -ate 1
Explanation
To ulcerate is to fester, or to develop into a terrible, painful sore. Ouch! In medical terms, when a wound ulcerates, it doesn't heal, but becomes worse — red, open, painful, and sometimes infected. Skin can ulcerate, resulting in bedsores or canker sores in the mouth, and internal wounds can also ulcerate, forming what's known as an ulcer, or open sore. The Latin root of both words, ulcus, means "sore."
