This article explores the significance of a word and the changes it undergoes in its form when it is placed in the hierarchy of grammatical constituents thereby forming a new word termed as vocabulary. This change or transformation is the result of affixations. Transformation becomes essential as the words learnt cannot be used as such in a context. One should have a clear understanding and the knowledge of the words before using them in a context; otherwise it would lead to a syntactic error. This article also includes a few tasks that would enable the students to actively participate in developing their vocabulary that would automatically boost up their confidence level and enhance their communicative competence.
