In Latin, dexter means right (as in right hand). The word for left hand is sinister.
Sinister (sinistra, sinistrum).
'Left' in Latin is 'Sinister' and 'Right' is 'Dexter'

Sinistra -ae. The word sinister is derived from it.
My guess: Dexter is Latin for right side. Sinister is Latin for left side.
The only sinister thing about left-handed people is the fact that sinister comes from the Latin word for left.
"What is left (as opposed to right)?" is an English equivalent of the Latin phrase Quid est sinister? The question also translates literally as "What is adverse (bad, hostile, perverse)," "What is auspicious (for Romans?" and "What is inauspicious (for Greeks)?" in English. The pronunciation will be "kwihd est see-NEE-ster" in Church and classical Latin.
There are almost a half dozen English language words that include 'left' in their meaning, and that trace their origins back to the ancient, classical Latin. One example is the adjective 'sinister'. The word is defined as 'evil or suggestive of evil'. But it also has a meaning of 'leftwardness'. For the 'sinister events' on a family's heraldic shield are found on the left side. And the word 'sinister' indeed tracks back to the Old French 'sinistre', and on further to the earlier source in the Latin 'sinister', or 'left-hand'. Likewise, the adjective 'sinistral' indicates the left side is uppermost in flatfish, and whorls go leftward in spiral shells. And it tracks back to the Old French or Medieval Latin 'sinistralis', which means 'of or relating to the left hand'. Additionally, the adjective 'sinistorsal' and the noun 'sinistrorse' find their origins in the Latin 'sinistrorsus', which refers to a 'twining spirally upward to the left'.
O. S. stands for "oculus sinister", which is Latin for "left eye". O. D. stands for "oculus dexter", which is Latin for "right eye".
OS is the abbreviation for left eye. OS stands for the Latin term, oculus sinister.
