词源

valid

valid: [16] Something that is valid is etymologically ‘strong’, and hence ‘effective’. The word comes via French valide from Latin validus ‘strong, effective’, which was derived from the verb valēre ‘be strong’ (source also of English valiant, valour, value, etc). The negative form invalid [16] also goes back to Latin, but its specific application to infirm people, differentiated with a distinct pronunciation, was introduced from French in the 17th century.=> valiant, valour, value
