I’m deviating from expressions because I find the etymology of the word interesting. It refers to being left- handed, and both of our children are dominantly left-handed. The root of the word sinister is the Latin sinistra, which refers to being left-handed. Left-handed evolved over time to mean evil, threatening, or unlucky. It has also been considered as meaning the person has been touched by the devil. On the other hand (so to speak) another web site explains, “There is something righteous about the right hand: it is supposed to point in the right direction and do everything right.” I’ve not noticed that our children have suffered any more than other left-handed people who have to deal with right-handed tools, etc., and I noted in sports that being left-handed (and left-footed in soccer) was an advantage.
