The word "not due" is not typically used as a stand-alone word with a specific etymology. Instead, it is a combination of two words: "not" and "due". Each word has its own etymology:
1. "Not": The word "not" is derived from Old English "nāt" or "nōt", becoming "not" in Middle English. Its origin can be traced back to the Proto-Germanic word *naihw ("not"), which is formed from the negative particle *ne- and *aihwaz ("ever, aye"). Similar words can be found in other Germanic languages.
2. "Due": The word "due" originates from Latin "dēbītus", meaning "owed" or "owing". It is the past participle of the verb "dēbēre" ("to owe").
