Causal sentences are sentences that express cause-and-effect relationships.
A cause-and-effect sentence is a sentence structure used to describe the relationship between cause and effect. It consists of two clauses, the first clause expresses the cause and the second clause expresses the effect. This sentence pattern is often used to explain the cause-and-effect relationship between events and help readers or listeners understand the logic of the development of things. By using cause-and-effect sentences, you can clearly express the causes and consequences of an event or action.
