In Turkish, 'karşılaştırma ekleri' are suffixes used to compare two things. They help you say if something is bigger, smaller, better, etc., than something else.
Use these forms when you want to compare people, objects, or situations in Turkish. For example, to say that one thing is more or less than another, or to express the highest degree (the most, the least).
