Is "-지 마십시오" the same thing as "-지 마세요" but more formal?

[jackisback7]

Exactly. It's typically used nowadays in the service industry, like a hotel, airlines when speaking to a customer.

[hansi735272]

what does 마십시오 mean?

[V375981]

Please do not

[sakuyaluigi]

Why isn't there an option to add "please"?

[sparklebunny]

I think politeness ("please") is implied in the formality of the ending -십시오 please correct me if I'm mistaken!

[CooperReid4]

No you're good. Another way you could say it is "속여지마요" but remember this one is a little less polite

[Ash-Fred]

"속이지 마요."

[youngween]

So whenever "지 마요" is added, the verb must be in a stem word form right?

[ph.16zdBK]

Now the please option is added

[Stella11209]

Because formality/politeness level can not be translated with the word "please". You have to see it just as a respectful word ending and not as a begging like "please" sounds

[Tilsii]

Is the present tense of this verb 속이어요 or 속여요

[Buchukimchi]

The dictionary form is 속이다 and the present tense would be 속여요.

[daphne2011]

look, duo, my pal, you deceived the boy so you deserve it

[giacomo-jimmy]

How would you say "I don't deceive?"
