Synonym discussion
Sense: noun/1
Climber is the broadest term: it covers anyone who ascends steep surfaces using ropes and technical gear, whether on a rocky crag or a high-altitude peak. Mountaineer is narrower and more prestigious — it suggests long expeditions on big mountains (often involving snow and ice) and a commitment to the culture of alpine travel. Hiker describes a person who walks on established trails for pleasure; a hiker rarely needs ropes or a harness, so calling a hiker a 'climber' would overstate their technical involvement. Trekker falls between hiker and mountaineer: a trekker covers long distances on foot through mountainous terrain (e.g., the Annapurna Circuit) but does not usually scale vertical rock or ice. In everyday speech, 'I'm a climber' implies ropes, effort against gravity, and a degree of risk. 'I'm a hiker' implies a walking stick and a packed lunch.

Etymology
Climber is formed from the verb 'climb' (from Old English climban, of West Germanic origin) plus the agent suffix '-er' (meaning 'a person or thing that does something'). The plant sense emerged by the 17th century, drawing on the same upward-movement image as the human sense.
