The degrees of comparison (tingkat perbandingan) berjumlah tiga tingkat, yaitu :

1. The positive degree (tingkat biasa)

2. The comparative (tingkat lebih/perbandingan)

3. The superlative (tingkat paling)

1. The positive degree is the most basic form of the adjective, positive because it does not relate to any superior or inferior qualities of other things in speech.
2. The comparative degree denotes a greater amount of a quality relative to something else. The phrase “Anna is taller than her father” means that Anna's degree of tallness is greater than her father's degree of tallness.
3. The superlative degree denotes the most, the largest, etc., by which it differs from other things.
