Morphology
The noun 'ulcer' clearly indicates a sore and 'decubitus' (from Latin meaning lying down/related to pressure) specifies the cause, so a learner who knows both constituents can infer it is a sore caused by prolonged pressure. Because 'decubitus' is a specialized medical/Latin term rather than a productive, everyday modifier, the connection is partially predictable but relies on technical knowledge.
Etymology
Decubitus ulcer comes from Latin words: decubitus meaning 'lying down' and ulcer meaning 'sore'. The name paints a simple picture — someone who lies in bed too long gets a sore from pressure, so today it means a sore caused by long pressure on the skin.
