Ordinals 'first' through 'third', the most common in Diu Indo-Portuguese, and often also 'fourth' through 'sixth' are not immediately derived from their corresponding cardinal numerals, i.e. they are suppletive: e.g. pimer 'first' vs. ũ 'one'. There is a strong tendency to use English ordinals (and, to a lesser extent, English numerals) in everyday speech, with the effect that non-English-derived ordinals are rather hesitantly formed and employed. A suffix -m is however part of the derivational repertoire of some speakers; -m attaches to cardinal numerals above six in order to obtain ordinals: e.g. oytm 'eighth' from oyt 'eight'.
