4.51 Suppose that all elementary sentences were given to me: then it can be asked simply: which sentences can I build from them? And those are all [the] sentences [that there are] and thus are they limited.

The last sentence here is translated by Ogden and Pears & McGuinness as if it meant what I have implied by the addition of the words in brackets , but these are absent from what Wittgenstein actually wrote. Perhaps this is significant. I don't know.
