Etymology
From Latin apricus (“sunny, having lots of sunshine; warmed by the sun”) + -ate. Apricus is derived from aperiō (“to open; to uncover”) (from Proto-Indo-European *h₂epo (“off, from”) + *h₂wer- (“to cover, shut”)) + -cus (suffix forming relational adjectives from nouns). Not cognate with apricot, although the latter term was also influenced by apricus.
