At this point you are way out of his zone of proximal development. Pointing out words to him is as useful as showing him the equations of particle physics or a score of the Magic Flute: it's way beyond his comprehension.

Imagine instead blocks with letters he can play with, which make sounds when he touches them. This is much closer to what he can comprehend. Imagine further that these blocks can be stuck together and that touching these block trains results in the syllables they make being vocalized.

Unfortunately, written English is extremely anti-phonetic, so the reading barrier might be lower if your native tongue is Spanish or something.
