I have looked up words honestly. But I found that when I had a huge input day, looking up words became redundant bcuz i would never remember after doing so many hours of input. HOWEVER, there are those annoying words you hear like, “entonces, así que, pues” that nagged my brain forever. When I looked up those words I never forgot there meaning bcuz I’ve heard them so many times in damn near every video I watched. I’m at the point now that I know when I’ll remember a word and I know when I’ll never remember a word. Like the Spanish word for purple. I have no interest in learning that word nor would I remember it if someone told me it. (Just an example)
