Somnolent vs soporific
Somnolent is sleepy. Soporific makes you sleepy.
The difference
Somnolent describes the one who is drowsy: a somnolent afternoon, a somnolent cat, a somnolent town where nothing moves after lunch. Soporific describes the cause: a soporific lecture, a soporific drug, a book you cannot get through because it puts you under. The two get swapped because both live near sleep, but one is the state and the other the agent.
Somnolent
Sleepy, or making you feel sleepy.
The somnolent village stirred only at noon.
Soporific
Making you sleepy.

Which one to use
