 Turning now to conjunction, the idea here is similar. Again, the fundamental idea is that the interpretation of the left conjunct can affect the interpretation of the right conjunct. A bit more formally, a pair of assignment functions \(\langle g,h\rangle\); is in the interpretation of a conjunction just in case there is an assignment function k such that \(\langle g,k\rangle\); is in the interpretation of the left conjunct and \(\langle k,h\rangle\); the right  conjunct.[17]  So note how interpreting the left conjunct changes the input sequence for the interpretation of the right conjunct. Again, this means that conjunction is internally dynamic, possibly affecting the interpretation of expressions in its scope. And again, that the output of interpreting a conjunction, here h, can differ from the input, here g, means that a conjunction is capable of affecting things outside of it and hence outside of the scope of that conjunction sign. Again, this is to say that conjunction is externally dynamic.
