in solxlanni, most of the words for each number are based the welsh words. with some deviation. numbers are said in a very simple way, the same way as welsh. for example '91' in welsh would be "nawdeg un" and in solxlanni it would be "naaw deg un", or '512' [cym]"chwech cant undeg dau" [slx]"chwec cant un deg du". agglutination is used when grouping thousands so '302,052' becomes "tricandumil e pumdegdu"
