Easy to mix with look-alikes

The spelling risk for null is neighbouring look-alikes ("num", "nur", …), not just typos; it is anumeral pronounced /nʊl/ ouvir^(fonte ?). Frequency #42,573 among 360 “N” headwords. 2 recorded senses keep meaning in play.

Our generated misspelling index lists 4 likely wrong-spelling variants for null, with forms such as "nlul", "nnull", and "nul". Every one of these variants traces to a single-character edit -- an added or dropped letter, a swapped consonant, or a vowel swap -- the kind of slip a spell-checker is built to catch. It also participates in 9 confusable-pair relationships, "num", "nur", "nun", and more, since the words sound or look close enough that writers reach for the wrong one mid-sentence.

Wiktionary doesn't record an etymology for this headword, leaving phoneme-to-grapheme mapping as the best guide to its spelling rather than a borrowing history. The correct Portuguese form is null, spelled N-U-L-L.
