Exploring Language Structure: A Student's Guide

Designed for these commencing to research linguistics, it is a full of life creation to 2 key features of the constitution of language: syntax (the constitution of sentences) and morphology (the constitution of words). It exhibits scholars in a step by step type the way to study the syntax and morphology of any language, by means of truly describing the fundamental tools and strategies, and supplying virtually a hundred useful routines in line with info from a wealthy number of the world's languages.
