 Ordinals are formed with the adjectival suffix "-a," quantities with the nominal suffix "-o," multiples with "-obl-," fractions with "‑on‑", collectives with "‑op‑", and repetitions with the root "‑foj‑".The particle "po" is used to mark distributive numbers, that is, the idea of distributing a certain number of items to each member of a group.Consequently, the logogram @ is not used (except in email addresses, of course)
