Gilaki or Guilaki (گیلکی) is one of the North-western Iranian languages spoken in Iran's Gilan province. Gilaki is diminishing among the younger generation especially in the cities and is being substituted by Persian. Gilaki language has many Farsi (Parsi) words within it; however the grammar is somewhat similar to some of the european languages such as English in that the adjective precedes the object. For instance: Apple Red in Farsi is similar to Red Apple in Gilaki.

Today Gilak poets are the only people who try to save the language by using its terms and expressions in their poems and writings. A large amount of Gilaki words and expressions are now forgotten and are not in use because of using their simpler instants in Farsi.
