font: English has two words font. The older, ‘basin for baptismal water’ [OE], comes from font-, the stem of Latin fons ‘spring, fountain’ (from which English also gets fountain). It may well have been introduced into the language via Old Irish fant or font (it was often spelled fant in Old English). Font ‘set of type’ [16] (or fount, as it is often also spelled) was borrowed from French fonte, a derivative of fondre ‘melt’ (whence also English fondant, fondu, and foundry).
