The limitation with flashcards is that you get the entire answer, not sure if there are flashcard apps with a hint function? I experimented with vocab training where you can peek the first two letters which helps jog the memory.

There’s a hint function on phrasing.app :) we’re launching the public beta this week sometime

In Anki, select the “Cloze” card type, and add hints with this syntax

    {{c1::answer::hint}} 

Try encoding the same information in multiple cards to train your brain to understand the concept rather than recognise the card. Good luck!

Clozemaster has something like that where you can get the first letter as a hint. I tried Anki for a few languages and would always burn out making cards. Clozemaster is nice because it puts the word in the context of a sentence and then has an “explain” function that uses ChatGPT to explain the grammar. And they group words by sets of frequency (100 most common, 500 most common, etc)

I've created a flashcard app with a hint function. I mention it in another comment.

Anki has two types of hint fields (and the CSS/JavaScript in Note Types is editable, so you can add your own functionality if this is insufficient)
