It's mysterious how the process of learning this strange language works – it's not as if Charles Wallace is thumbing through a dictionary or putting a babelfish in his ear. It seems that all that's needed for him to pick up this new language is time and attention – it's almost as if it's something he already understands, he just has to match up the new means of expression with what he already knows.

This might be foreshadowing the way that the humans fight against IT with words: nursery rhymes, snatches of historical documents, etc.

Mrs. Whatsit sighed. "Explanations are not easy when they are about things for which your civilization still has no words." (5.10)
How do you explain something without words? It seems like Meg & Co. are engaged in a perpetual game of charades, trying to figure out what's going on around them without being able to just talk it out.
