'Connective', as the name suggests are demonstrated as the words that primarily intend or function to join two words, clauses, phrases, or sentences. These words are quite similar to conjunction or a relative pronoun and function to add the connectivity among the ideas by presenting the relation between them by offering the reason, consequence, contradiction, etc. It also helps in maintaining the smooth flow of ideas in a logical and coherent manner. Some examples would include: besides, finally, further, hence, afterward, as soon as, etc.
