In R and S configuration, the R stands for rectus and the S stands for sinister. Similarly, do the D and L descriptors in the Fischer-Rosanoff convention stand for something?

Dextro (right) and levo (left). (I learned it as "laevo", but I don't see that spelling in a quick Google search.)

$\begingroup$ In Rosanoff's paper of 1906, the two series were designated as Delta and Lambda from which D/L was derived. For a brief history, see ursula.chem.yale.edu/~chem220/chem220js/STUDYAIDS/history/… $\endgroup$ Commented Jan 13, 2019 at 0:54
