Build a strong foundation of Japanese with a high-frequency grammar and real-world phrases.
The structure の in Japanese acts as a nominalizer, turning a verb, adjective, or clauses into a noun-like phrase. This allows the speaker to refer to actions or qualities as objects or subjects.
When combined with particles like は or が, it creates more specific meanings. allowing the speaker to talk about actions or qualities as if they were objects or subjects. While they may look similar, they have distinct roles in a sentence:
・のは: Used when the nominalized action or quality serves as the topic or subject of the sentence, often drawing attention to it.
・のが: Used when the nominalized action or quality is the subject being evaluated or preferred in the sentence.
On its own, の can also nominalize verbs and adjectives in general contexts, without additional focus.
While the base の nominalizes the action, のは and のが add layers of meaning by specifying the grammatical role of the noun phrase in the sentence.
