Meaning & History
Back-formation from pease, originally an uncountable noun meaning "peas" that was construed as a plural, combined with Middle English nute, note, from Old English hnutu, from Proto-Germanic *hnuts (“nut”) (compare West Frisian nút, Dutch noot, German Nuss, Danish nød, Swedish nöt, Norwegian nøtt), from Proto-Indo-European *knew- (compare Irish cnó, Latin nux (“walnut”), Albanian nyç (“a gnarl”)).
