Questions & Answers about kaisya ni tuitara ansin desu.
Why does this sentence use に after 会社?
に marks the destination with movement verbs. In 会社に着いたら, 会社に tells us that 会社 is the place you arrive at.
What does 着いたら mean, and why use たら?
着いたら is the past-tense + たら form of 着く (to arrive). The たら conditional can mean "when," "once," or "if." Here it means "once I arrive at the company..."
How is たら different from other conditionals like と or なら?
- と often signals an automatic or inevitable result and isn’t used for volitional actions.
- たら is more flexible: it handles time sequences (“once/when”) and hypothetical situations.
- なら frames a condition more like a topic (“if it’s the case that…”).
In “会社に着いたら安心です,” たら emphasizes that relief follows arrival.
What part of speech is 安心, and why add です?
安心 is a な-adjective (also used as a noun meaning “relief” or “peace of mind”). Adding です makes the sentence polite and asserts the state: “It’s relief.”
Can I use the verb 安心する instead here?
Yes. 安心する is the verb “to feel relieved.” You could say 会社に着いたら安心します. Using 安心 + です treats it as a descriptive state—more concise and still polite.
Could I drop です and just say 会社に着いたら安心?
In casual speech, yes. 会社に着いたら安心 (plain style) is perfectly natural among friends. です simply adds politeness.
Is there an implied subject in this sentence?
Yes. Japanese often omits the subject when it’s understood. Here, the unspoken subject is I (the speaker), who will feel relieved upon arrival.
