climb: [OE] The original notion contained in climb seems not to have been so much ‘ascent’ as ‘holding on’. Old English climban came from a prehistoric West Germanic *klimban, a nasalized variant of the base which produced English cleave ‘adhere’. To begin with this must have meant strictly ‘go up by clinging on with the hands and feet’ – to ‘swarm up’, in fact – but already by the late Old English period we find it being used for ‘rising’ in general. The original past tense clamb, which died out in most areas in the 16th century, is probably related to clamp ‘fastening’ [14]. => clamp, cleave
