In Turkish, 'üstünlük ve eşitlik dereceleri' are ways to compare things: showing if something is more (comparative) or as much as (equality) another thing.
Use these forms in Turkish when you want to compare people, objects, or actions, for example, to say something is bigger, smaller, faster, or as good as something else.
