There is a long debate going on for years that either language shapes thought or thought shapes language. Many thinkers, philosophers, psychologists, anthropologists, and linguists have tried and reasoned to support either the superiority of language over thought or of thought over language. This article attempts at proving that language and thought are combined to make, mould, effect, and modify language and thought further. A research was conducted on two different groups of students and teachers. One group of teachers and students dealt with literary studies while the other group of students dealt with linguistics studies. The students of literary studies were affected by the themes and ideas which they studied in their text books, while the students of linguistics were not affected by the themes and ideas rather they had learning of structure of language. Both groups had dealt with English. This research proves that formation of meanings by language and thought combined has affects. I call this theory of formation of meanings.
