The Portuguese ordinal numbers from 1 to 10 (apart from 9) are used in Creole with phonetically adapted forms. Actually, only the first five are generally used. From 6 onwards it is common to use the cardinal numbers instead, sometimes the kel di séti ‘the seventh’, kel di oitu ‘the eighth’, kel di nóvi ‘the ninth’ construction. From 'ten' upwards cardinal numbers must be used.
Already in Portuguese, the etymological relationship between the ordinal numbers up to 'ten' and the corresponding cardinal numbers is not transparent any longer.
