「おはいください」か。
“Ohairi kudasai” ka.
(“Ohairi kudasai,” huh.)

「おはいおねがいします」でも正しいのかな?
“Ohairi onegaishimasu” demo tadashii nokana?
(I wonder if “ohairi onegaishimasu” would be correct, too?)

Decoder’s Notes

Detective

It looks like Oliver thinks that;
“ください (kudasai)=please” and “おねがいします (onegaishimasu)=please”.

So, is “お入り おねがいします (ohairi onegaishimasu)” correct, too?

In English, both “ください (kudasai) and “おねがいします (onegaishimasu) can often be translated as “please.”
So, does that mean “お入り おねがいします (ohairi onegaishimasu) is correct, too?

Today, let’s solve this mystery together!

“おください (Ohairi kudasai)
“お
おねがいします (Ohairi onegaishimasu)

To explain the difference between these two expressions, let’s use let’s use the following simple rule of thumb for now:

ください (kudasai) → often used together with a verb
おねがいします (onegaishimasu)” → basically used with a noun

That’s it!

The key word here is “お入り (ohairi).” “お(Ohairi) comes from the verb “入る (hairu)”, meaning “to enter,” and is a respectful expression used when referring to someone else’s action. You don’t need to worry about the detailed grammar here. Just remember:”お(ohairi)” originally comes from the verb “入る (hairu).” That’s enough for now.

Since “お入り (ohairi)” comes from a verb, we use “ください (kudasai)” in this case. Thus, “お入り ください (ohairi kudasai)” is a polite way to ask someone to enter.

So:
“おり ください (Ohairi kudasai)” →〇
“おり おねがいします (Ohairi onegaishimasu)” →×

The Clue

There are many other expressions that follow the same pattern as “おり ください (ohairi kudasai)”. For example:

  • きください (Okaki kudasai): “Please write it down.”
  • おかけください (Okake kudasai): “Please have a seat.”
  • ちください (Omachi kudasai): “Please wait.”

Wait a minute.
When I want some water at a convenience store or restaurant, I can say: “水、ください (mizu, kudasai)“, which means “can I get some water?”


ください (kudasai) → often used together with a verb
おねがいします (onegaishimasu)” → basically used with a noun
That’s what we learnt here.

In “水、ください (mizu, kudasai)“, “水 (mizu)” is a noun, but we’re still using “ください (kudasai)“. So what’s going on?

Actually, there is another rule hiding behind “ください (kudasai)” and “おねがいします(onegaishimasu)“.

“お入り ください (Ohairi kudasai)” and “水、ください (mizu, kudasai)
They both use “ください (kudasai)“, but something is different. We’ll uncover that mystery in the next case.
