Questions & Answers about Makspulsen påvirker pulssonen.

Why are makspuls and pulssone written as one word each?

Because Norwegian normally writes compound nouns as one word.

• makspuls = maks
  • puls
• pulssone = puls
  • sone

This is much more consistent in Norwegian than in English. Where English might use maximum heart rate or heart-rate zone, Norwegian usually prefers a single compound word.

A useful rule: in Norwegian compounds, the last part is the main noun. It decides the basic meaning and how the word behaves grammatically.

Why is there a double s in pulssonen?

Because the compound is built from puls + sone.

• puls ends in s
• sone starts with s

When they join, both letters stay, so you get pulssone.

Then the definite ending -en is added:

• pulssone → pulssonen

So the spelling is completely regular.

Why do both nouns end in -en?
