Etymology
From Middle French martingale, from Occitan martegalo, feminine form of martegal, an inhabitant of Martigues, which is from Latin maritima. Possibly merged with Spanish almártaga. The meaning in gambling may come from an old usage of à la martingale to mean absurdly or foolishly.https://people.math.harvard.edu/~ctm/home/text/class/sem/html/home/notes/martingales/martingales.pdf
