Our generated misspelling index lists 12 likely wrong-spelling variants for internal, with forms such as "inetrnal", "innternal", and "intenral".

It also participates in 8 confusable-pair relationships, "internet", "interval", "Interpol", and more, since the words sound or look close enough that writers reach for the wrong one mid-sentence.
