Fractions and proportions (hálfur, helmingur)

Reading a will and dividing an inheritance requires careful language. Before we dive into fractions, let's look at some essential vocabulary for handling an estate, such as erfðaskrá (will), erfingi (heir), and the verb skipta (to divide).

The lawyer reads the will today.
Lögfræðingurinn les erfðaskrána í dag.
We have to divide the property equally between the heirs.
Við eigum að skipta eigninni jafnt milli erfingjanna.

The Noun Helmingur (Half)

In Icelandic, there are two different ways to say "half." The first is the masculine noun helmingur. You use this when treating "the half" as a distinct share or object. It often appears with the definite article as helmingurinn (the half) and is frequently followed by the preposition af (of) plus the dative case to say "half of" something.

The widow gets half of the inheritance.
Ekkjan fær helminginn af arfinum.
The heirs own half of her house.
Erfingjarnir eiga helminginn af húsinu hennar.

The Adjective Hálfur (Half)

The second way to say "half" is the adjective hálfur. You use this when "half" directly modifies a noun, similar to saying "a half share" or "half the family" in English. Like all Icelandic adjectives, hálfur must agree with the gender, number, and case of the noun it describes.

She owns a half share in the real estate.
Hún á hálfan hlut í fasteigninni.
Half the family is angry about it.
Hálf fjölskyldan er reið út af því.

It is common to see both the noun and the adjective used in the same sentence to express similar ideas in different grammatical ways.

The widow gets half of the estate because she owned half the house.
Ekkjan fær helminginn af dánarbúinu af því að hún átti hálft húsið.

Other Fractions and Proportions

For other common fractions, Icelandic uses masculine nouns ending in -ungur, such as þriðjungur (a third) and fjórðungur (a quarter).

Each heir gets a third of the money.
Hver erfingi fær þriðjung af peningunum.
He owns a quarter in the company.
Hann á fjórðung í fyrirtækinu.

Finally, when discussing the overall split, ratios, or percentages, you can use the neuter noun hlutfall (proportion).

The proportion is completely wrong.
Hlutfallið er alveg rangt.
