KK: /maʊnˈtɪrɪŋ/
The activity of climbing mountains, often involving skills like rock climbing and ice climbing.
Mountaineering requires both physical strength and mental determination.
Mountaineering is formed from "mountain" (from Old French *montaine*, meaning a large natural elevation of the earth's surface) and "-eering" (derived from the verb form indicating the action of engaging in a particular activity). The word refers to the activity of climbing or exploring mountains.
Think of 'mountain' as a large elevation and '-eering' as engaging in an activity — mountaineering means actively climbing or exploring mountains.
