Making Plans Together: 같이 -아/어요 & -(으)ㄹ까요?
Make invitations with 같이 -아/어요 and ask “Shall we?” or “Shall I?” with -(으)ㄹ까요?, with form rules, examples, and six practice questions.
Introduction & Review
You already know polite -아/어요 statements. Add 같이 (together) and an inviting tone to suggest a shared activity. Use -(으)ㄹ까요? to ask for the other person’s agreement: “Shall we …?” The same ending can offer your own help: “Shall I …?”
N = noun; V = action verb; A = descriptive verb. Romanization is a reading aid.
Today’s Grammar / Explanation
V = action verb. Remove 다 first. After a vowel, add ㄹ까요: 가다 → 갈까요? 먹다 has a consonant: 먹을까요?
Keep a final ㄹ without adding another one: 만들다 → 만들까요? Some irregulars change: 듣다 → 들을까요? 걷다 → 걸을까요?
같이 + the familiar polite form makes an invitation: 같이 가요. The context and intonation distinguish an invitation from “We go together.”

자, 이제 시작합시다.A firmer “Let’s…”, often said to a group. It can sound bossy to older people; -(으)ㄹ까요? is softer.

Common mistakes
Choose an action that people can do intentionally. 같이 예뻐요 describes being pretty; it is not a normal “Let’s be pretty” suggestion. -(으)ㄹ까요? also has an “I wonder whether” use, but today’s practice focuses on invitations and offers.
보 ends in a vowel, so add ㄹ까요: 볼까요.
찍 ends in a consonant, so add 을까요.
Stems ending in ㄹ just add 까요: 만들까요.
To accept, say 좋아요 or 네, 같이 마셔요 — don’t repeat -(으)ㄹ까요.
