A connective is any word which indicates the semantic relationships between items in the discourse. Some examples of semantic relationships and the connectives that may indicate them are :
- Concession (the second element is surprising in view of the first): Although John's always late and spends half the day playing computer games, they've decided to promote him. Examples of concession connectives include: but, although, however
- Addition (the second element is the same in some way as the previous one. In the example below the meaning structure is problem + problem + problem): The chassis was rusted, and a brief inspection of the engine showed that the vehicle was clearly not roadworthy. Moreover, no road tax had been paid for three years. Examples of addition connectives include : and, in addition, moreover
- Consequence (the following element is the result of the previous one) : The train was an hour late leaving, so that we missed our connection in Birmingham. As a result, we didn't get to the hotel until 11pm. Examples of connectives expressing consequence include : so, so that, consequently, as a result
As these examples show, connective expressions may come from a range of word classes, eg here there are conjunctions (but, although, and, so that), adverbials (however, in addition, moreover, as a result) or prepositions may also be connectives, eg : We went out in spite of the rain; We didn't go because of the transport strike.
