Using の instead of が I have learnt from basic Japanese that が is used with adjectives or intransitive verbs. However, it is common to see in writing that の is used instead. For example, 日本語の分かる人 instead of 日本語が分かる人 which I learned. What is the reason for using の over が? Is there some rules that dictate which to use? I have heard that sometimes in a long sentence when there is already が in the first part, の will be used in place of が if there exists.
