Adjectives in English Grammar. How to put adjectives in the correct order in a sentence? We use adjectives to describe the quality of something, such as colour, age, origin, material, opinion and material. Native and fluent speakers will normally (hopefully) put adjectives in the right order naturally relying on the sound of the sentence rather than trying to think of the rule. In the meantime, generally speaking we will follow this order: opinion – size – age – colour – origin – material.
