Approximate numerals and their formation
Numerals that show a quantity by estimate are approximate numerals. They are made with -tacha, -lab, -larcha: o‘ntacha (about ten), yigirmatacha (about twenty); o‘nlab (dozens), yuzlab (hundreds), minglab (thousands); o‘nlarcha, yuzlarcha (some tens, some hundreds). Approximation is also expressed by pairing numerals: ikki-uch (two or three), besh-olti, o‘n-o‘n besh (ten to fifteen). Such pairs are written with a hyphen. The suffixes are joined to the numeral. -lab (o‘nlab, yuzlab) shows an inexact but large quantity.
“Estimate”: estimate the beans in a jar (o‘ntacha, yigirmatacha...) and then count to check.
