I do usually need words that have the same root "وزن" but I don't have a way to search in the whole language for them.
Classical Arabic dictionary are not arranged in word alphabetical order they are actually arranged in root alphabetical order
meaning once you open the dictionary on the root , you will find all words related to that root in that page and the following pages,( regardless of the starting letter of those words related to that root)
for example i used the root W Z N = وزن in this online dictionary https://www.almaany.com/ar/dict/ar-ar/%D9%88%D8%B2%D9%86/
the rest of the page show all possibilities to use the root W Z N
