Origin

Late Middle English (as a verb in sense 3 of the verb): from Latin scandere 'climb' (in late Latin 'scan (verses)'), by analogy with the raising and lowering of one's foot when marking rhythm. From 'analyse (metre)' arose the senses 'estimate the correctness of' and 'examine minutely', which led to 'look at searchingly' (late 18th century).

This was first used as a verb in the sense ‘analyse the metre (of verse)’. The source is Latin scandere ‘climb’ by comparison with the raising and lowering of one's foot when marking rhythm. From this the sense developed into ‘estimate the correctness of’ and ‘examine minutely’, which in turn led to ‘look at searchingly’ in the late 18th century. See also scale

Origin

Late Middle English (as a verb in scan (sense 3 of the verb)): from Latin scandere ‘climb’ (in late Latin ‘scan (verses)’), by analogy with the raising and lowering of one's foot when marking rhythm. From ‘analyze (meter)’ arose the senses ‘estimate the correctness of’ and ‘examine minutely’, which led to ‘look at searchingly’ (late 18th century).
