词源

词源 1
Feminine nominative singular of Latin novus (“new”). The feminine is used since stella (“star”) is feminine; thus nova is a shortening of nova stella (“new star”), first used in this sense in 1573 by Tycho Brahe.
词源 2
Blend of novum + Latin -a. From the Latin -a suffix used as the plural suffix form for singular words ending with -um (an inflection of -us).
