Pech.

Etymology tree Proto-Indo-European *pik-der. Proto-Italic *piks Latin pixbor. Proto-West Germanic *pik Old High German pëh Middle High German pëch German Pech Inherited from Middle High German pëch, bëch, from Old High German pëh, bëh, from Proto-West Germanic *pik (“pitch, tar, wood resin”), from Latin pix. The form is unusual as it shows unshifted p-, but shifted -ch, even though the shift of initial p- to pf- occurred later than that of postvocalic -k to -ch. Theodor Frings therefore considered that the word was at first restricted to West Central German along the Rhine (which lacks the pf-shift) and only spread to Upper German slightly later when the shift was no longer active. (Middle High German pfich occurs only once in a Central German text from the 14th century and is thus probably a hypercorrection.)
