An example from korean: 이름은 is shown as a new word even if you know 이름. and even if you didn't have 이름, you cannot edit 이름은 when adding it, you need to delete and add again to fix it. Please add the ability to merge words (something like an "add to existing word" button) or the ability to edit existing words. This will also avoid double counting the known words.
