What does pain mean?
Pain is a central English word for both physical discomfort and emotional suffering. As a noun, it can describe the sharp or persistent sensation of an injury, the ache of illness, or the distress caused by loss, fear, or conflict. It also appears in expressions describing difficulty or effort, such as taking pains to do something carefully. As a verb, pain means to cause suffering or to hurt someone, and in informal speech it can mean to irritate or annoy a person. The word is common in medical, emotional, and figurative contexts, although some related expressions, especially 'pain in the neck,' are informal and mildly dismissive. Its broad range of uses makes it useful for describing suffering of many kinds, while more specific terms such as ache, soreness, distress, or anguish may convey particular qualities.

Where does pain come from?
The word entered English through Old French from Latin poena, meaning 'penalty' or 'punishment.' In medieval English, its meaning broadened from punishment or penalty to physical suffering and then to emotional anguish. The same Latin root underlies related English words such as penalty, penance, penitence, and pensive.
