AはBが adjective
Describe a part or feature of the topic
You’ll be able to describe a particular part, feature, or aspect of a topic with は and が.
この犬は耳が大きいです。
kono inu wa mimi ga ookii desu.
What do you think this sentence means?
This dog has big ears.
Describe one feature of a topic
は marks the overall topic, and が marks the part or feature directly described by the adjective. Here, the dog is the topic and its ears are what 大きい describes.
Natural English often uses “has” or “have” for this pattern, but Japanese is structured more like “As for A, B is...”.
私は髪が短いです。
watashi wa kami ga mijikai desu.
I have short hair.
Mark the topic with は and its feature with が
Put は after A, the overall topic. Put が after B, the part or aspect that the adjective directly describes, and then add the adjective. The feature can be a body part, one part of an object, or a broader characteristic of a place or thing.
この家は庭が広いです。
