Sense: adjective/1
Sleepy, drowsy, tired, weary, and dozy all describe a lack of energy or alertness, but they differ in cause and intensity. Sleepy specifically refers to the need for sleep — your eyes feel heavy and you may yawn. Drowsy suggests a state between awake and asleep, often caused by medication, warmth, or illness. Tired is broader, covering physical or mental exhaustion from any activity. Weary implies long-lasting fatigue from ongoing effort or worry. Dozy is informal British English for lightly sleepy, especially in a warm relaxing setting. For example: 'Elena felt sleepy after the big lunch.' 'The patient was drowsy from the painkillers.' 'The hikers were tired after climbing the mountain.' 'Rohan grew weary of the daily arguments.' 'The cat looked dozy by the fireplace.'

Etymology
Comes from Old English slǣpig (sleep + the suffix -y meaning 'full of'), related to slǣpan meaning 'to sleep'. The original sense 'full of sleep' dates back to medieval times. The meaning 'quiet with little activity' for describing places developed later, around the 1800s. Related words in German (schläfrig) and Dutch (slaperig) share the same root.
