crown: [12] Crowns appear to have been named essentially from their circular shape. The word’s ultimate source, Greek korónē, simply meant ‘something curved’ (it came from the adjective korōnos ‘curved’, which was a relative of Latin curvus ‘curved’). Latin borrowed it as corōna ‘circular garland’, and passed it on via Old French corone and Anglo-Norman corune to English.

Latin also derived a verb from it, corōnāre, which ultimately became the English verb crown and also, of course, formed the basis of English coronation [14]. Other English descendants of Latin corōna (which itself became an English word in the 16th century) are the two diminutives coronet [15] and corolla [17] (source of corollary), coroner [14] (originally an ‘officer of the crown’), and coronary.

The use of crown for certain coins (based of course on their being stamped with the figure of a crown) dates in English from the 14th century; it is also reflected in such coin names as Swedish krona and Danish and Norwegian krone.
