The 'r' was lost somewhere in the Proto-Norse phase and the result
is 'haust' in Old Norse. In Icelandic the word came to be applied
only to the harvest _season_. In the mainland languages I think they
still use the word (in some form like 'höst') to mean 'harvest'.
In Faroese the form is 'heyst' - and I think it is only used for
the season.
