dough

Dough comes from Old English dāg, from Proto-Germanic *daigaz, tracing back to Proto-Indo-European *dʰeyǵʰ-, meaning 'to knead, form, mold.'

It moved through Middle English forms like dow, dogh, and dagh before settling as dough. The slang sense meaning 'money' appeared in the mid-19th century, though exactly why remains unclear.

It's cognate with German Teig, Dutch deeg, and Swedish deg, all of which still mean 'dough' in their own languages — a whole family of Germanic tongues that never stopped talking about bread.
