What does lethargic mean?

Lethargic is an adjective meaning lacking energy, alertness or the will to act. It describes a state rather than a personality: an energetic person can still feel lethargic during an illness. The Cambridge entry for lethargic treats it as both a medical and an everyday descriptor of sluggishness. Two senses matter here. The physical sense points to a body that is slow and heavy; the figurative sense points to an organisation or market that has stopped moving. Where you mean a lasting habit of avoiding work, lazy is the sharper word, because lethargic implies a cause such as illness, heat or exhaustion. Lethargic is also the wrong choice for ordinary sleepiness after one late night; a plainer phrase like a bit tired fits that situation better.

How do you use lethargic in a sentence?

Lethargic is an adjective, so it either precedes a noun or follows a linking verb. The pattern you choose changes the emphasis. Attributive use labels the thing, while predicative use describes a passing moment.
