masc nom sg of ādicca (noun)
Etymology. From ā- (toward) + √dic (to show, point), literally 'that which points toward'; the concrete imagery is of the sun's rays pointing earthward. Related to Sanskrit ādityá (Aditya, sun god, 'the unconstrained one'), from ádi 'beginning, free' — though Pali reanalyzed the word through the prefix ā- and a root dic.
