virtue

virtue: [13] Latin virtūs ‘bravery, strength, capacity, skill, merit’ was derived from vir ‘man’ (source also of English virago ‘manlike woman’ [14] and virile [15]), and so etymologically it denoted ‘manliness’. It passed into English via Old French vertu. Derivatives include virtual [14] which, preserving another semantic aspect of its source, originally meant ‘having power, in effect’, but by the 17th century had evolved into its modern sense ‘so in effect or in essence’; and virtuoso [17], which was borrowed from Italian and goes back to the ancestral sense ‘skill’.
=> virago, virile, virtual, virtuoso
