Frequently Asked Questions
It is a loanword from Greenlandic Inuit (Kalaallisut) 'nunataq'.
Yes, though rarely. It can describe an isolated community, idea, or tradition that persists despite surrounding cultural or social changes.
No. A nunatak is a rock peak attached to the ground, protruding through a glacier or ice sheet. An iceberg is a floating mass of ice that has broken off from a glacier.
The standard English plural is 'nunataks'. The Greenlandic plural 'nunat' is sometimes used in very technical contexts.
