valueyoudaoicibaDictYouDict[value 词源字典]
value: [14] To have value is etymologically to be ‘strong’ or ‘effective’, and hence to have ‘worth’. The word was borrowed from Old French value, a noun use of the feminine past participle of valoir ‘be worth’. This was descended from Latin valēre ‘be strong, be of value’, which also produced English avail [13], available [15] (which originally meant ‘advantageous’, and was not used for ‘accessible for use’ until as recently as the 19th century), convalesce [15], valency [19], valiant [14], valid, and valour [14].
