Example #1: how to say “moonlight” in Japanese
kon’ya wa gekkou ga totemo utsukushii – 今夜は月光がとても美しい (こんやはげっこうがとてもうつくしい)
The moonlight is very beautiful tonight.
Below are the new words used in the example sentence.
- kon’ya – 今夜 (こんや) : a noun meaning ‘tonight’ in Japanese. This can also work as an adverb almost anywhere in a sentence. In the example, this works as a noun.
- wa – は : a binding particle working as a case marker or topic marker. In the example, this works as a topic marker after “kon’ya” to put a focus on it.
- ga – が : a case particle used to make the subject word or the object word in a sentence. In the example, this is used after “gekkou” to make the subject in the sentence.
- totemo – とても : an adverb of degree meaning ‘very’, ‘much’, ‘so’, or such in Japanese. In the example, this works before “utsukushii” to emphasize its meaning.
- utsukushii – 美しい (うつくしい) : an i-adjective meaning ‘beautiful’ in Japanese.
This is a typical usage of “gekkou”. In the example, this works together with the case particle, “ga”, to become the subject in the sentence. When we want to say “moonlight” in Japanese, this noun is a good option.
Example #2: another usage of “gekkou”
watashi tachi wa gekkou no shita wo arui ta – 私達は月光の下を歩いた (わたしたちはげっこうのしたをあるいた)
We walked in the moonlight.
Below are the new words used in the example sentence.
- watashi – 私 (わたし) : a pronoun meaning ‘I’ in Japanese.
- tachi – 達 (たち) : a suffix used after a noun or pronoun to make its plural form. In the example, this is used after “watashi” to make its plural form, “watashi tachi”, which means ‘we’ in Japanese. Learn more about Japanese plural.
- no – の : a case particle joining two nouns. Normally, the first one can work as a modifier to describe the second. In the example, this join “gekkou” and “shita”. The formed phrase literally means ‘the underneath of the moonlight’ in Japanese. It has been translated as just ‘in the moonlight’, though.
- shita – 下 (した) : a noun meaning ‘underneath’ in Japanese.
- wo – を : a case particle used to make the object word in a sentence. In the example, this is used after “gekkou no shita” to make the object in the sentence.
- arui – 歩い (あるい) : one conjugation of the verb, “aruku“, which means ‘to walk’ in Japanese. In the example, it has been conjugated for the better connection with its following word.
- ta – た : an auxiliary verb used after a verb, adjective, or auxiliary verb to make its past tense form. In the example, this is used after “arui” to make its past tense form, “arui ta”.
This is another typical usage of “gekkou”. In this example, it works together with “no shita” to say “in the moonlight” in Japanese.
