Rare enough to double-check

a priori is uncommon French outside the top frequency list, classed as anadjective, transcribed \a pʁi.ɔ.ʁi\. Rarity is why readers land here mid-draft. Gloss: "Connu d'après des données antérieures à l'expérience ; su en s'appuyant sur les principes de l’intellect ; intuitif.".

No misspelling variants are generated for a priori in our index, and the word's spelling is regular enough that our generator found nothing worth flagging. Our confusable-pair dataset has no match for it, since no other headword is close enough in sound or shape to pair with it.

No explicit etymology string is stored for this entry, so spelling patterns must be inferred from the word's phoneme-to-grapheme mapping rather than from a documented borrowing chain. The correct French form is a priori, spelled A- -P-R-I-O-R-I.
