There are other numeral derivatives: thus —

a. multiplicative adverbs, as dvís twice, trís thrice, catús four times;

b. adverbs with the suffixes dhā (1104) and ças (1106): for example, ekadhā́ in one way, çatadhā́ in a hundred ways; ekaças one by one, çataçás by hundreds;

c. collectives, as dvítaya or dvayá a pair, dáçjataya or daçát a decade;

d. adjectives like dvika composed of two, pañcaka consisting of five or fives;

and so on; but their treatment belongs rather to the dictionary, or to the chapter on derivation.
