accusative singular masculine of visākha (noun)
Analysis. vi- (apart, asunder) + -sākha (branch): literally 'having branches apart', hence 'forked' or 'branching'; the name of a star group whose asterism resembles a forked branch.
Etymology. From vi- (apart) + √sākh- (branch, fork), akin to Sanskrit śākhā and related to Old English scōh. The nakṣatra name is fixed in Vedic astronomy, where Viśākhā's asterism (the stars α and τ Librae) was seen as a branch or fork in the sky. The prefix vi- captures the sense of multiple branches spreading apart.
