Take for instance the following, relatively uncommon terms:
- Froward [Forward]
- Obverse [Observe]
- Perquisite [Requisite/prerequisite]
- Effront [Affront]
- Ingenuous [Ingenious]
- Infarction [Infraction]
Is there a term which collectively refers to words that look misspelled but are in fact valid words which are not just alternative forms of the 'more common' words?
Clearly, the words appear normal to one who is accustomed to them. I'd hazard that only 'froward' and 'infarction' are words that, to some native English speakers who aren't well read, might appear as misspelled words. {Others, like apposite [opposite] are far more common, but appear to be incorrectly spelled to those only presently learning English.}
