somnolent

"Somnolent" is a formal, elegant word that describes a state of sleepiness or drowsiness. It has two closely related senses — one describing a person or creature that feels sleepy, and one describing a place or atmosphere that makes you feel like sleeping. It's not a word you'll hear in casual conversation every day, but you'll find it in literature, medical contexts, and formal writing.

1adjectivefeeling sleepy

When a person or animal feels very drowsy and heavy-eyed — not quite asleep, but struggling to stay awake — you can describe them as somnolent. Think of how you feel after a big meal on a warm afternoon: that slow, foggy, half-asleep feeling is exactly what this word captures.
