nubile: [17] In modern English, nubile is generally used as a facetious synonym for ‘sexy, attractive’, but etymologically it means ‘suitable for marriage’. It comes from Latin nūbilis, a derivative of nūbere ‘take a husband’. This has also given English nuptial [15] and connubial [17], and is related to nymph. => connubial, nuptial, nymph[nubile etymology, nubile origin, 英语词源]
