Connective words, also known as conjunctions or linking words, are essential in writing and speaking. They help to join ideas, sentences, or phrases, making the text flow smoothly. Examples include words like "and," "but," "because," and "however." These words clarify relationships between thoughts, such as addition, contrast, or cause and effect. Using connective words enhances coherence in communication. For instance, in a sentence like "I wanted to go for a walk, but it started to rain," the word "but" shows a contrast between the desire and the reality. Proper use of connective words can improve understanding and engagement in any form of communication.
