A number of points need to be borne in mind here. First, the same conjunction may be used to signal different relations, depending on the context. Second, these relations can be expressed by a variety of means; the use of a conjunction is not the only device for expressing a temporal or causal relation, for instance. In English, a temporal relation may be expressed by means of a verb such as follow or precede, and a causal relation is inherent in the meanings of verbs such as cause and lead to.
