For instance: I could make a card with sapo on one side and the dictionary definition anfibio anuro de cuerpo rechoncho y robusto, ojos saltones, extremidades cortas y piel de aspecto verrugoso on the other.
Oh no. That's not what I mean at all.
Again, I CANT read a dictionary yet. I'm A2 lol. But it's still useful!!
Read what you can. At A2 level you should have already mastered the words noun, verb, adverb, adjective, preposition (etc. etc). How many categories is the word in?
How many definitions? Is this a flexible word with 50 definitions or is it a simple word with 3 related definitions under one subheading?
What's the frequency count of the word? Are there any synonyms or antonyms that you recognize?
Are there any "related" prepositions with the word? In German, it's "helfen bei" (which is different than English "help with"), the native level dictionary makes it clear which preposition is closely associated to the word.
Even though I can't read definitions, there's still a TON of information here that I learn from.
I NEVER make the Anki card from a native dictionary.
No, I make very simple Anki cards. I then spend lots of time in the dictionary (native and bilingual) to learn more about the word. Anki remains a simple one definition per word flashcard.
