We couldn't generate a plausible misspelling set for sillier, and the word's spelling is regular enough that our generator found nothing worth flagging. It is not paired with a close-neighbour confusable in our dataset, a sign it's visually distinctive enough not to be mixed up with another word.
Wiktionary doesn't record an etymology for this headword, so its spelling is easiest to reason about phoneme by phoneme, absent a documented history. The correct English form is sillier, spelled S-I-L-L-I-E-R.
