Brisker: Sorry, thought I explained that. Amaylus literally means hard work or toil. It is much harder for a native English speaker to use a Hebrew Artscroll than an English one. Whether an English speaker should use a Hebrew artscroll for that reason is debatable. I would personally think it’s not real amaylus batorah, but merely making it harder on yourself for no reason, but you can’t deny that the English speaker is being amel more than if he were to learn it in English.
ps: I actually know someone who used a Hebrew artscroll rather than English in Mesivta for that reason. Thank God, he can now learn just fine without one.
