How to make the base structure of the translator's dictionary?

Question

SQL

Good day.
Now I am writing my own mini translator, I think about the structure of the database for it, but the main snag is the following.
there is the word apple (translation apple) there is the word apples, apple, etc. how can you connect them and say that the word apples is just the plural of the word apple, maybe someone has already had a similar experience.
