This work tries to offer a historical review of the studies that have been carried out on the morphology and syntax of the Galician language. However, the main objective of this contribution is to give a panoramic outlook of the guidelines of the Galician grammatical production, not an exhaustive list of the works published until now. After analyzing the historic delay with which Galician started to be scientifically studied, and the causes of this delay, a critical survey of the main thematic lines and orientations on the studies of Galician morphology and syntax is given. The work ends with a presentation of the challenges that Galician linguistics must deal with, facing the future.
