Questions & Answers about asa ni koohii o nomu to, shigoto no kouritsu ga ii desu.

Why is に used after 朝? Can we drop it or use は instead?

In Japanese, に marks a specific point in time, so 朝に means “in the morning” or “at morning.” You can sometimes drop に (just say 朝), especially in casual speech, turning it into an adverbial time phrase.

• If you use は (朝は), you’re marking “morning” as the topic: “As for mornings, …” That shifts the nuance to talking about mornings generally rather than specifying “when (someone) drinks coffee in the morning.”

What does the と after 飲む mean? Is it the same as たら or ば?

Here, 飲むと is the conditional と, meaning “when/whenever (you) drink.” It indicates a general or predictable result: “Whenever you drink coffee in the morning, (then) …”

• たら also means “when/if,” but often refers to a specific instance (“If/when I drink coffee tomorrow, …”).
• ば is another conditional form with a slightly more formal or hypothetical nuance.
  Using と stresses that the result (good efficiency) reliably follows the action.

Why is の used in 仕事の効率?

The particle の links two nouns, showing possession or association. 仕事の効率 literally means “the efficiency of work” or “work efficiency.” Without の, the relationship between “work” and “efficiency” would be unclear.
