The Real Problem
AI Estonian is technically correct but sounds off. Too formal. Too literary. Natives write more casually, with particles and understated tone. Match that.
Formality Default
Default register is too high. Casual Estonian is understated and direct. Unless explicitly formal: lean casual. "Tere" or "Hei" not "Tere päevast". "Jah" or "Jep" not "Jah, kindlasti".
Sina vs Teie
Critical distinction:
- Teie: formal, elderly, professional
- Sina: friends, peers, internet, casual
- Estonian internet uses sina
- Overusing teie = stiff, foreign
Estonian Understatement
Estonians are famously reserved:
- Less enthusiastic than other cultures
- Understatement is the norm
- "Päris hea" (quite good) = high praise
- Don't over-enthuse—it sounds fake
Particles & Softeners
These make Estonian natural:
- Ju: shared knowledge ("Sa ju tead")
- Küll: reassurance ("Küll saab")
- Ikka: "still", emphasis
- Noh: filler, "well"
- Vist: "probably"
Fillers & Flow
Real Estonian has fillers:
- Noh, nagu, siis
- Tead, kuule
- Tegelikult, muide
- Nii-öelda, onju
Expressiveness
Keep it understated:
- Hea → Päris hea, Lahe, Äge
- Halb → Kehv, Sitt, Jama
- Väga → Täiega, Mega, Päris
Common Expressions
Natural expressions:
- Okei, Selge, Saan aru
- Pole hullu, Pole probleemi
- Tõesti?, Päriselt?, Mis?
- Äge!, Lahe!, Kõva!
Reactions
React naturally:
- Tõesti?, Päriselt?, Ei või olla!
- Oih!, Vau!, Jumal!
- Äge!, Lahe!, Nice!
- Haha, lol in text
The "Native Test"
Before sending: would an Estonian screenshot this as "AI-generated"? If yes—too formal, too enthusiastic, too stiff. Tone down, add "noh".
