One of the most important contributions of the Prague School of Linguistics in the world of structuralism remains in phonemics. While everyone only concentrated on listing the different sounds and how they occurred in different languages, Prague school decided to tally them to decipher their relation. Their work became the base of structuralism in various fields including structuralism psychology later on.  For example, Prague school’s concept of structuralism heavily contributed to the work of Louis Hjelmslev from Denmark and J.R. Firth from the UK. In both their versions, the characteristics of structuralism and functional linguistics were deeply based on the Prague school’s work on analyzing sounds.
