“Let’s eat sometime” is not a booking

Sometimes lunch really is the question

Imagine someone asking 밥 먹었어?—“Have you eaten?”—and the exchange ending with a simple yes. Now imagine the same question from someone counting how many portions of takeaway to order. In the second case, whether you have eaten is useful information. Treating it as a greeting alone could lead to the wrong order.

A 2016 curriculum study published by Korea's National Institute of Korean Language reviews a table of cultural teaching content from an earlier study. It lists equivalents of “Where are you going?” and “Have you eaten?” as greeting examples. This supports teaching a greeting use of the meal question. It is neither a finding that every such question is empty politeness nor a measure of how reliably Koreans keep appointments.

Knowing the greeting category adds a possible reading. It does not remove the job of ordering food in front of you. What was happening when the question was asked still matters.

A meal already eaten and a meal to come

밥 먹었어? asks whether a meal has happened. 언제 밥 한번 먹자 proposes eating together at some future point. Both concern food, but they ask the listener to do different things. The curriculum table cannot establish that the second expression is always just a greeting too.

Here is an invented farewell to compare. A says, “Let's get something to eat sometime.” B replies, “Sure. Get home safely.” An interest in meeting again has been expressed, but there is no date or place to enter on a calendar. Nothing in the exchange warrants adding either “They have no intention of meeting” or “They will definitely meet next week.”

The Japanese mata kondo also needs its preceding turn when translated into Korean. A reply postponing today's invitation and a farewell mentioning a future meeting deal with different conversational tasks. A shared theme of eating does not make the two expressions fixed translations of each other.

Getting a proposal onto the calendar

Now A sends another sentence: “How about lunch next Tuesday, at the place opposite the office?” A date, part of the day and location have become candidates. If B replies, “I can't; I'll be away for work,” no arrangement has been made. Even a detailed proposal still needs an answer before it becomes an agreed plan.

The public farewell without a date or place resembles the first exchange. Its mention of meeting again does not supply booking information. By contrast, the meeting scene proposing next Tuesday offers a candidate the other person can respond to. The question asks you to recognise that proposal, without jumping ahead to everyone's agreement.

That is why these public scenes sit together here. The comparison is not a contest over whether Korean or Japanese speakers are more direct. It lets us inspect how the information available changes between a scene without a date and one that proposes a date.

Leave the gaps in the translation

Our first invented exchange can use 今度、ご飯でも食べよう in Japanese and “Let's get something to eat sometime” in English. Adding “next week” would change the offer. Conversely, reducing the second proposal, with its Tuesday lunch and restaurant, to “See you sometime” would discard information needed to arrange the meeting.

If you would like to eat together, you can take the conversation a step further: “Sounds good. When would suit you?” Waiting for an answer before booking a table also reduces the burden of deciding, alone, whether the first remark was sincere or merely polite.
