Special Counting Words (нумератив)
Tajik has some special words used with numbers. These are called classifiers or numeratives. They are often left out when translating into English. Examples-
дона: piece, unit
сар: head (for counting animals)
ҷуфт: pair
бандча: bundle, bunch
нафар: person (for counting people)

Examples:
панҷоҳ сар гӯсфанд: fifty head of sheep, fifty sheep
се-чор нафар моҳигир: three to four fishermen
нуҳ дона тухм: nine eggs

Alternatively, the classifier то (or та) can be added as a suffix to the number.
Ду дона китоб дорам. I have two books.
Дуто китоб дорам. I have two books.

With units of time and measurement no classifier is used.

сад сол: one hundred years
