Questions & Answers about Brillestyrken måles i dioptrier.

Why is brillestyrken written as one word?

Because Norwegian usually forms noun + noun combinations as compound words.

• brille = glasses / spectacles
• styrke = strength, power

So brillestyrke means something like glasses power or lens strength. Then brillestyrken is the definite singular form: the glasses power / the prescription strength.

This is very normal in Norwegian. English often uses separate words where Norwegian prefers one compound.

Why does brillestyrken end in -en?

The ending -en marks the noun as definite singular.

The base noun is:

• en brillestyrke = a glasses strength / a prescription strength

The definite form is:

• brillestyrken = the glasses strength / the prescription strength

In Norwegian, the definite article is often attached to the end of the noun instead of being a separate word like the in English.

Why is it brille- and not briller-, since English says glasses?

In Norwegian compounds, the first noun is often in its base form, not necessarily the form that would sound most natural in English.

So:

• brille = glasses / spectacle
• brillestyrke = glasses strength

Even though English uses the plural word glasses, Norwegian commonly uses brille- in compounds. This is just how Norwegian builds many compound nouns.
