To learn how compound propositions are true or false depending on the truth or falsity of their component propositions.
There is the idea of setting up a code or convention or dictionary between atomic sentences and capital letters.
There are compound sentences, each of which has a main connective which connects its components.
There are five sentential logical connectives:
'∼' which translates back to 'it is not the case that...'
'&' which translates back to '... and ...'
'∨' which translates back to '... or ...'
'⊃' which translates back to 'if... then ...'
'≡' which translates back to '... if and only if ...'

Symbolizing compound propositions. Learning about logical connectives, and the notion of the main connective. Recognizing different constructions in English which have the same underlying logical form. Paraphrasing the English into a standard form.
It is the next step in learning how to symbolize. Main connectives are very important-- they are central to symbolization, they are central to the semantics, and they are central to derivations.
