Cymbeline has a good head for vocabulary; he can go at whatever pace is comfortable for her. Eventually they've passed things like pronouns and "walk" and "sit", skipped over the sign alphabet which doesn't seem to interest her, and moved on to slightly more complicated words. Prepositions, nouns like "bird" and "fish" and various body parts, verbs that are a little trickier to draw or mime like "see" and "hear" and "want".
