To extend the range of sentences by using a wider range of connectives, linking main and subordinate clauses using conjunctions, and linking main clauses using connecting adverbials
A connective is a word, or group of words, that joins or connects clauses. Connectives can be conjunctions or adverbials.
A clause is a group of words that either forms a sentence on its own or forms part of sentence; it must contain a verb and usually a subject. For example, there are two clauses in the sentence: ‘The boy crossed the road slowly, although he was in a hurry.’ The main clause of the sentence is the part that could stand alone (single-clause sentences are always main clauses): ‘The boy crossed the road slowly’. The subordinate clause or sub clause is dependent on a main clause to make sense: ‘although he was in a hurry’ couldn’t stand alone. Each clause contains a verb (‘crossed’ and ‘was’) and a subject (‘boy’ and ‘he’).
Conjunctions are used to join words, phrases or clauses within a sentence. In the example above, the conjunction ‘although’ is used.
A connecting adverbial links one main clause to another, usually across separate sentences. For example, ‘However’ in: ‘The boy was in a hurry. However, he crossed the road slowly’. Connecting adverbials can be adverbs (single words, e.g. ‘therefore’, ‘consequently’ or ‘however’), adverbial phrases (multiple words without a verb, e.g. ‘even so’) or adverbial clauses (multiple words with a verb, e.g. ‘while this was happening’).
