Do you have to use more particles when you speak formal korean ?
I already know all the particles you use when you speak korean, but I was asking myself, when you speak formal korean, do you have to include in the sentences more particles in order to put the sentence in formal language ? If it is, what are the particles ?

Hi Auréliane,

If I get what you are asking, in order to make sentences formal, there are some basic rules you can easily apply.

1. Start your sentence with the word '당신/그/그녀/그들'(you/he/she/they) instead of using '너/걔/걔네'(you/he/she/they in an informal way).

2. Always finish with the word '요' or '다'.

Ex. 1) 당신은 이곳에 들어오실수 없어요 (or 당신은 이곳에 들어오실수 없습니다).
= you cannot enter this place.

Ex. 2) 그는 주말마다 거기서 봉사 해요 (or 그는 주말마다 봉사를 합니다).
= he volunteers there every weekends.

~다 is more formal and polite than ~요.

Hope it helps.
