Mutual invitation
Two same-age classmates have talked politely and one says, “우리 말 놓을까요?”
A mutual switch to banmal can be natural.The invitation makes the change explicit instead of assuming that same age automatically creates familiarity.

BANMAL GUIDE
Banmal is about relationship norms, not permission from age alone.
What banmal means. Banmal (반말) is casual, non-honorific speech. Being older does not automatically give someone a universal right to use it, and being the same age does not guarantee that both people will immediately switch to it.
Look at the current speech pattern. If both people already use polite speech, an abrupt one-sided switch can feel presumptive. An explicit invitation such as “말 편하게 하세요” can change the situation, but tone, role, and setting still matter.
Work and school can override closeness. A boss, teacher, senior, client, or formal group may keep polite speech even when people are friendly. In uncertain situations, maintaining polite speech and letting the relationship establish its own norm is the safer starting point.
WHEN PEOPLE ASK ABOUT BANMAL
“Can I use banmal?” usually means more than “Are they younger?”
Banmal depends on the relationship. Relative age can influence expectations, but closeness, mutual speech habits, permission, and the setting all change what sounds natural. Someone using banmal with you does not automatically mean you should switch too.
When you are unsure, keep polite speech. Everyday 해요체 is a useful starting point while you learn how the other person prefers to speak. Use the finder above when you need a context-specific starting point rather than a single age rule.
BANMAL IN PRACTICE
This finder decides whether a casual switch is socially established.
The Banmal Finder is intentionally narrower than the Speech Level Finder. It asks whether using banmal with this person is a reasonable move now, based on mutual speech habits, invitation, closeness, role, and setting. It does not choose among all Korean styles or claim that every sentence becomes appropriate once banmal is possible.
COMPARE
One-sided switch
An older coworker uses banmal with you, but you have not been invited to do the same.
Keep polite speech for now.The other person’s casual speech may reflect role or age expectations; it is not automatically reciprocal permission.
REAL DIALOGUE
Asking to switch mutually
This invites a shared change. It is less presumptive than suddenly removing -요 endings.

Shall we speak casually with each other?
COMMON MISTAKES
- Assuming that younger people must accept banmal from anyone older.
- Reading one casual sentence, text message, or joke as a permanent change in the relationship.
- Using banmal in a formal meeting because the same people use it privately.
USE WITH CARE
말 편하게 하세요 can be context-sensitive: it may invite relaxed speech generally, or simply ask you not to be overly formal. Listen to the other person’s examples and ask when the intended level is unclear.
