moi
/moi/
Hi. Also bye. Say it once and it is hello, say it twice and you are leaving
Quick answer
Moi means hi. Doubled - moi moi - it means bye, and Finns switch between the two without thinking about it.
- It dominates southern and central Finland; terve is more common in the east and around Oulu, and moro belongs to Tampere.
- Age shapes the choice: Helsinki shop staff will say moi to a young customer, hei to a middle-aged one and päivää to a pensioner.
What moi means
Moi is the ordinary, friendly hello. It is not slang, not rude, and not restricted to young people. It is simply the most common casual greeting across most of the country.
The doubling rule is the part that catches people. A single moi opens; moi moi closes. The same works with hei: hei to arrive, hei hei to leave. Nobody explains this and everybody does it.
Why moi changed
There is no written-versus-spoken split here in the way there is with mä and minä. Hei and moi are both standard - they differ by region, by age and by how warm you are being, not by register.
The formal end of the scale is a different word entirely: hyvää päivää, "good day", which is what you use in an office you have never been to before, or with someone considerably older.
How Finns actually use moi
Geography decides more than politeness does. Kotus, the Institute for the Languages of Finland, has written about the split: hei is the most common greeting nationally, but it is challenged by terve in North Karelia and by moi in Helsinki, and moi dominates most of southern and central Finland between friends.
Terve, moro and morjens carry a gender skew as well as a regional one - see moro.
Age is read off the person in front of you. A shop assistant in Helsinki will typically say moi to someone young, hei to someone middle-aged, and päivää to a pensioner - three greetings in one shift, chosen in the second before speaking.
Moi is not new. Heikki Paunonen's dictionary of Helsinki slang records it as a greeting from the 1910s, and it spread as a fashionable greeting over roughly fifteen to twenty years.

moi in a conversation
The mistake everyone makes with moi
Hearing moi at the end of a conversation and answering as though a new one has started. It is the goodbye.
Assuming moi is nationwide neutral. In Tampere you will hear moro; in North Karelia, terve. Answering in kind is a small thing that reads as paying attention.
Questions people ask about moi
What does moi mean in Finnish?
Hi. Said twice - moi moi - it means bye.
What is the difference between moi and hei?
Very little in meaning. Hei is the most common greeting nationally; moi dominates southern and central Finland and is the Helsinki default. Both double up to mean goodbye.
Is moi formal or informal?
Informal but not slangy - it is fine with colleagues, neighbours and shop staff. For a first meeting in a formal setting, or with someone much older, hyvää päivää is safer.
Why do Finns say moi twice?
Doubling turns the greeting into a farewell. Moi opens a conversation, moi moi ends it, and the same happens with hei and hei hei.
What do people say instead of moi in other parts of Finland?
Terve in the east, around Oulu and in eastern Lapland; moro and morjens in Tampere and Pirkanmaa. Terve and moro also skew male.
How old is the word moi?
Older than it sounds. Heikki Paunonen's dictionary of Helsinki slang records moi as a greeting from the 1910s.
Is moi a bad word?
Safe with colleagues, neighbours, shop staff and friends. For a formal setting or a much older stranger, hyvää päivää is the safer choice.
