In Wiyot, the numbers 20-49 are constructed in a kind of mathematical formula:
|20||2 x 10||rri'duva = "two beyond [ten]"|
|21||(2 x 10) + 1||rri'duva hulurr ve goutsurr = "there are two beyond [ten] + one over"|
|30||3 x 10||rrikva = "three beyond"|
|32||(3 x 10) + 2||rrikva hulurr ve rri'durr = "there are three beyond [ten] + two over"|
|40||4 x 10||rra'ma = "four beyond [ten]"|
|43||(4 x 10) + 1||rra'ma hulurr ve goutsurr = "there are four beyond [ten] + one over"|
Like the words for numbers 5 and higher, the full forms of these numbers include the verb hulurr "there are so many", so e.g. rri'duva hulurr really means "there are twenty".
The numbers shown on this page (with the verb hulurr in their full forms) are used for counting people and many animals, and for abstract counting (counting numbers, but not any specific physical object).
To count other types of objects in the world (long skinny objects, flat objects, roundish objects, built objects, etc.), units of time (number of times/repetitions, days, years, etc.) and other concepts, Wiyot uses several different sets of endings (called classifiers).
