thirst: [OE] The etymological notion underlying the word thirst is of being ‘dry’. For it goes back ultimately to the Indo-European base *trs, *tors- ‘dry’, which also produced Latin torrēre ‘parch’ (source of English toast, torrid, etc). From this was formed the prehistoric West Germanic noun *thurstu, which has evolved into German durst, Dutch dorst, and English thirst.
