Question 1

What is the function of は in this sentence?

Accepted Answer

は is the topic‐marking particle. It tells us that 私 (“I”) is the topic we’re talking about, not necessarily the grammatical subject in the strict sense. Everything that follows comments on or describes 私.

Question 2

Why do we use を after 仕事?

Accepted Answer

を marks the direct object of the verb. In 仕事をします, 仕事 (“work”) is what is being “done” by the verb します (“to do”), so を shows that relationship.

Question 3

Where does 毎日 go, and can I move it elsewhere in the sentence?

Accepted Answer

毎日 means “every day” and functions as a time adverb. It most naturally appears right before the verb:  
• 私は 毎日 仕事をします.  
You can also say:  
• 毎日 私は 仕事をします.  
• 私は 仕事をします 毎日.  
All are grammatical, but each word order shifts the emphasis slightly.

Question 4

What’s the difference between します and する?

Accepted Answer

する is the plain (dictionary) form of “to do.”  
します is its polite present/future form (the “-masu” form).  
• Use します in formal or polite situations.  
• Use する in casual conversations with friends or family.

Question 5

Can you omit 私 in this sentence? When is that allowed?

Accepted Answer

Yes. Japanese often drops pronouns when context makes the subject clear. If it’s obvious you mean “I,” you can simply say:  
• 毎日 仕事をします.  
Omitting 私 makes the sentence sound more natural in everyday speech when there’s no ambiguity.

Question 6

Is Japanese word order rigid? For example, could I say 仕事を毎日します?

Accepted Answer

Particles give Japanese flexibility in word order.  
• 仕事を毎日します is grammatically correct and emphasizes 仕事.  
• 毎日仕事をします emphasizes the frequency (every day).  
Neither order is wrong; you choose based on what you want to highlight.

Question 7

What’s the difference between 仕事をします and 働きます?

Accepted Answer

Both can mean “to work,” but:  
• 仕事をします literally “do work,” focusing on the act of doing tasks or assignments.  
• 働きます is a single verb meaning “to work” or “to be employed,” emphasizing being at work or holding a job.  
Example:  
- 工場で働きます。I work (am employed) at a factory.  
- 昨日、レポートのために仕事をしました。Yesterday, I did work for my report.
