Interesting, I wonder if he also memorized all the irregular verb tenses? If so that is a serious feat.

For example, future tense in the 2nd person adds “ás” to the end of the verb. Pensar becomes pensarás. But, there are irregulars. You’d think the verb salir would be salirás (if you were memorizing), but it actually it saldrás

Seems like an incredible feat that goes beyond memorizing a dictionary. Unless Spanish scrabble maybe has specific rules around verb tenses and whatnot?
