Why, yes we can!
Seb's new thing is spelling out words. Not too sure when exactly this started but he now will just state a word, for example, "drop" and spell it out phonetically. He does this all over the place. For example, we'll be in the car and he'll say a word and then attempt to spell it out or we'll be at the dinner table. He requires some assistance at times but for the most part, he's doing a pretty good job!
