Polovica, tretjina, dvojno: fractions, multiples — and the dual when two are compared

A fraction, a multiple and a difference are three different tools, and mixing them up is expensive. For example: “Tretjina razreda je bila bolna, polovica pa na izletu” — A third of the class was sick, and half was on a trip. A rule from the Slovenian course: worked out on examples, not memorized as a wording.

How it works

A fraction, a multiple and a difference are three different tools, and mixing them up is expensive.

A fraction is built with -ina: tretjina, četrtina, petina. Half is a word of its own, polovica. The word after them takes its 'of what' shape: tretjina ljudi, petina plače. The verb stays singular: Tretjina razreda je bila bolna.

A multiple is an adverb in -krat: dvakrat več, trikrat manj. There is also the bookish dvojno: dvojno plačilo.

A difference goes through za: za tretjino več, za polovico manj. It is easy to confuse with a multiple: dvakrat manj is two times less, while za dva manj is two fewer.

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
