1. Definition + Rich Everyday Explanation
Worn out (adjective / phrasal verb past participle) = no longer usable or in good condition because of too much use; extremely tired and without any energy left after hard work or activity; (figurative) no longer interesting, convincing, or effective because repeated too many times.
Picture your favourite T-shirt that you’ve worn every weekend for three years — the colour is faded, there are holes under the arms, the fabric is thin: it’s completely worn out. Now imagine yourself after a full day of teaching, running between classes, answering questions, and then correcting homework until midnight: you collapse on the sofa, feeling you have zero energy left. That’s the same powerful feeling people mean when they say they’re worn out.
MEANING 1: Physically Damaged / No Longer Usable — VERY COMMON
When we talk about things, worn out describes objects that have suffered from long, heavy, or constant use. The material becomes thin, broken, torn, faded, or stops working properly. Everyone immediately understands this meaning — it’s the most concrete and visual one.
MEANING 2: Extremely Tired / Exhausted — VERY COMMON
For people, worn out means you feel totally drained — physically, mentally, or emotionally. It’s stronger than ordinary tiredness. After intense physical effort, long hours of concentration, emotional stress, or dealing with difficult situations, you feel you simply cannot continue. This is probably the meaning native speakers use most often in daily conversation.
MEANING 3: Overused and No Longer Effective (figurative)
We also use worn-out about ideas, jokes, excuses, arguments, or stories that have been used so frequently that they have lost their power, freshness, or believability. Just like an old shoe that no longer works well, the idea no longer “works” on listeners.
Examples from the street:
- “These trainers are completely worn out“. → My shoes are destroyed from too much use, time to throw them away
- “After the marathon, I was absolutely worn out“. → I felt totally exhausted, couldn’t even stand
- “That excuse is worn out, try something new”. → Your reason is old and boring, nobody believes it anymore
