Lacking comfort; providing no ease, relief, or consolation; bleak, cold, or desolate in feeling.
From 'comfort' (Latin 'confortare': strengthen) + '-less' suffix (Old English, meaning 'without'). Creates the opposite meaning through a native English suffix.
The '-less' suffix is one of English's oldest tools—it was productive over 1,000 years ago and still works perfectly today to negate any noun, which is why 'comfortless' feels natural even if we don't use it often.
