mye or mange?

Norwegian has two words for much / many / a lot of:

• mye goes with things you cannot count: mye tid, mye snø, mye vann, mye kaffe. It is also an adverb: Det regnet mye (It rained a lot), and it comes before comparatives: mye eldre (much older).
• mange goes with countable nouns in the plural: mange turister, mange barn, mange venner.

Questions work the same way:

• Hvor mye koster det? (How much does it cost?)
• Hvor mange barn har du? (How many children do you have?)

Fixed phrase: Takk så mye! (Thank you very much!)

Tip: if the noun after the gap is a plural form, choose mange; if it is a mass noun or there is no noun at all, choose mye.
