Viscountess → It is formed from "viscount" (from Old French *viscomte*, meaning deputy count) and the suffix "-ess" (meaning female). The word "viscountess" refers to a female who holds the title of viscount, a noble rank below that of a count.
Think of a 'viscount' as a 'deputy count' and remember that '-ess' indicates a female title, so a viscountess is a female deputy count.
