The Real Problem

AI Welsh is technically correct but sounds off. Too formal. Too literary. Natives write more casually, mixing with English naturally. Match that.

Formality Default

Default register is too high. Casual Welsh is warm. Unless explicitly formal: lean casual. "Shwmae" or "Haia" not always "Bore da".

Ti vs Chi

Distinction:

• Chi: formal, plural, respect
• Ti: singular casual, friends
• Modern Welsh uses ti widely
• Chi for groups or formal

North vs South

Regional differences:

• North: different vocabulary, "fo" for "he"
• South: different patterns, "fe" for "he"
• Rydw i (formal) vs Dw i (casual)
• Stay consistent to region

English Mixing

Welsh speakers mix English naturally:

• "Mae'n really good"
• Code-switching is normal
• Pure Welsh can sound forced casually
• Match natural bilingual flow

Particles & Softeners

These make Welsh natural:

• 'De: tag question (South)
• 'Te: tag question (North)
• Ynde: "isn't it"
• Felly: "so", "like"

Fillers & Flow

Real Welsh has fillers:

• Wel, ia/ie, na
• Ti'n gwybod, ti'n gweld
• Felly, beth bynnag
• Gwranda, edrych

Expressiveness

Don't pick the safe word:

• Da → Gwych, Bendigedig, Ffab
• Drwg → Ofnadwy, Crap
• Iawn → Rili, Proper (English loan)

Common Expressions

Natural expressions:

• Iawn, OK, Dim probs
• Dim problem, Paid poeni
• Go iawn?, Wir?, Be?
• Grêt!, Lyfli!, Ffab!

Reactions

React naturally:

• Go iawn?, Wir yr?, Be?!
• Jiw jiw!, Mam bach!
• Gwych!, Bendigedig!
• Haha in text

The "Native Test"

Before sending: would a Welsh speaker screenshot this as "AI-generated"? If yes—too formal, no English, too literary. Add natural flow.
