Questions & Answers about Latteren er høy.
Because Norwegian often marks definiteness at the end of the noun instead of using a separate word.
- latter = laughter
- latteren = the laughter
So -en is doing the job that the does in English.
Because latter is a common gender noun in Norwegian, not a neuter noun.
Its basic forms are:
- en latter = a laugh / a laughter
- latteren = the laugh / the laughter
If it were a neuter noun, the definite ending would usually be -et, but that is not the case here.
