Economy in language has a strong controlling function over the whole system, something which is carried out with the least possible cost in terms of energy. The concept of economy- a tenet or tendency shared by all living organisms may be referred to as 'the principle of least effort', which consists of the objective of the use of minimum amount of effort that is necessary to achieve the maximum results. This principle operates in linguistic behavior at the very core of linguistic evolution. The aim of this paper is to highlight the role of economy in linguistic landscape in the theoretical framework of Columbia School of Linguistics (CSL) also formally known as Form Content Linguistics. The theoretical basis of the theory of CSL is a chain of scholarly descent from Ferdinand de Saussure and Andre Martinet. It started from Prague School and reached to the Columbia School of Linguistics under the steward leadership of Prof. William Diver who reared and nurtured this theory at Columbia University through further research. The data for the present study was collected through photography method.
