At the moment I have my fictional language written down in a notebook, but as the vocabulary increases its becoming harder and harder to find words.
I am adding new words all the time, so writing them in alphabetical order doesn't last long.
How can I keep a track of this language and still be able to find the words I need?
Edit: I have seen this question has been marked as a possible duplicate, but it is different as I am also open to paper-and-pencil methods.
