pain

The word “pain” means an unpleasant physical sensation caused by injury or illness. In plain terms, physical or emotional suffering, or, informally, an annoyance.

“Pain” is pronounced PAYN (/ˈpeɪ̯n/ in IPA).

Here is “pain” used in a sentence: “She felt a sharp pain in her lower back.”

Depending on how it is used, “pain” can be a noun and a verb.

The word “pain” comes from Latin. From Old French peine, ultimately from Latin poena, "punishment" — the same root that gives us "penalty" and "penal.".

“Pain” is a very common word in modern English, usually learned at around the B1 level.

They sound identical but mean very different things. 'Pain' is an unpleasant physical or emotional sensation, as in back pain. 'Pane' is a flat sheet of glass in a window or door, as in a window pane. They are homophones, so spelling and context are the only ways to tell them apart.

Doctors often divide pain into acute pain, which is short-term and linked to a specific injury, and chronic pain, which lasts for months or longer. Pain is also described by how it feels, such as sharp, dull, throbbing, or burning, and the term extends to emotional pain, meaning deep distress.

Pain cannot be measured directly like temperature, because it is a personal experience. Instead, clinicians use rating scales, asking you to score it from zero to ten or point to faces showing distress. These tools help track how severe the pain is and whether treatment is helping over time.

Although it feels unpleasant, pain serves a vital protective purpose. It warns you of injury or illness and makes you stop harmful activity, pull away from danger, or seek help. People who cannot feel pain are at serious risk of unnoticed injuries, so the sensation, while unwelcome, is genuinely useful.
