Rosalind is of debated origin. The Germanic form derives from hros (horse) and lind (tender, soft) — meaning "tender horse." By the medieval period, folk etymology linked it to rosa (rose) and linda (beautiful) — "beautiful rose."
Shakespeare's As You Like It (c. 1599) features Rosalind as one of his most loved heroines — the witty, cross-dressed exile in the Forest of Arden. The Nobel laureate Rosalind Franklin (1920-1958), who imaged DNA's double helix structure with X-ray crystallography, gave the name modern scientific weight.
Rosalind reduces to seven — the number of literary keenness.
