Questions & Answers about asita no asa ni ie no souzi wo suru.
Why is の used between 明日 and 朝?
の connects two nouns to show a possessive or attributive relationship. Here, 明日 (tomorrow) modifies 朝 (morning), forming 明日の朝 (“tomorrow morning”).
Why do we use に after 朝, and can it be omitted?
に marks a specific point in time when an action occurs. 朝に means “in the morning.” In casual speech, you can drop に (e.g. 明日の朝家の掃除をする), but including it is clearer and more common in writing.
Why is there の between 家 and 掃除?
家の掃除 is a noun phrase meaning “house cleaning.” The の shows that the cleaning belongs to or concerns the house.
What role does the particle を play after 掃除?
を marks 掃除 as the direct object of the verb する, indicating what is being done.
Why do we say 掃除をする instead of just 掃除する?
Both are correct. 掃除する is a compound (suru-verb), while 掃除をする treats 掃除 explicitly as a noun object of する. They’re interchangeable, though 掃除をする can slightly emphasize the action.
How is 家の掃除をする different from 家を掃除する?
Both mean “to clean the house.” 家の掃除をする focuses on the activity (“house cleaning”), whereas 家を掃除する directly treats the house as the object. The nuance is subtle, and either form is natural.
Why is there no subject in this sentence?
Japanese often omits the subject when it’s clear from context. Here, the speaker (“I” or “we”) is understood without needing 私が or 私たちが.
Why does the sentence end with する?
Japanese follows Subject-Object-Verb (SOV) order. Verbs, including する, always come at the end to complete the thought.
