שלום כולם, As you can see I'm very new to this forum, so sorry if this is the wrong place for my question, but I thought I'd just tag along with this old thread about infinitives. Here a question that might sound stupid, but seriously, I can't find any rule to it. With infinitives, how do you know which vowel to use after ל? Why is it lilmod, but ledaber and la'asot? Is there a rule and if so, what is the rule? בתודה מראש!
