Numbers from 1-10, 11-20, and multiples of ten.
It is important to note that numbers between the multiples of ten (21-29, 31-39 etc.) are formed by first saying the smaller number, e.g., 43 = triåfjurti (3-and-40).
It is common to use the noun in the singular form with numbers, as in tri-fjur moān (Dreijer 1944; ISOF 16758) ‘three-four months (lit. month)’. This is regarded as an Estonian influence.
