"The woman is tall."
Translation:여자는 키가 큽니다.
Is the 가 in 키가 the subject particle? Is that why 여자 can only take the topic particle here?
yeah it says it in the lesson, that you put the subject particle on 키 when you are talking about a human/person's height only and then to use the words big/small instead of high and low like when talking about buildings and mountains
