Welsh Classroom Phrases for Adult Learners
On this page
Welsh classroom phrases are not decorative extras. They let you keep the lesson moving when you miss a word, need another example or want to risk an answer. Start with Dw i ddim yn deall - “I do not understand” - and Unwaith eto, os gwelwch chi'n dda - “Once again, please”.
The most useful phrases solve recurring problems. Learn a small set by function, not a long alphabetical list. When the same moment appears in class, the situation itself becomes your memory cue.
Ten Welsh classroom phrases worth learning first
| Welsh | English | Use it when |
|---|---|---|
| Bore da | Good morning | The class begins |
| Dw i ddim yn deall | I do not understand | You have lost the meaning |
| Unwaith eto, os gwelwch chi'n dda | Once again, please | You need a repeat |
| Yn arafach, os gwelwch chi'n dda | More slowly, please | The words are running together |
| Beth mae hyn yn ei olygu? | What does this mean? | A word or sentence is unfamiliar |
| Sut mae sillafu hynny? | How do you spell that? | You need the written form |
| Sut mae dweud ... yn Gymraeg? | How do you say ... in Welsh? | You know the idea in English |
| Ga i ofyn cwestiwn? | May I ask a question? | You want to interrupt politely |
| Dw i ddim yn siŵr | I am not sure | You want to attempt an answer |
| Diolch am yr help | Thank you for the help | Someone has helped you repair an answer |
Do not try to learn all ten at once. Choose two that solve your most common classroom problem, then add another when those come automatically.

Ask for repetition without ending the conversation
Unwaith eto, os gwelwch chi'n dda asks for the whole thing once more. If speed is the problem, Yn arafach, os gwelwch chi'n dda asks for slower speech. The second request is more precise and therefore easier for the other person to answer.
Try to identify where understanding stopped. You can repeat the part you did hear, then raise your voice slightly at the gap. That shows active listening and may bring a shorter, more useful repair than hearing the entire explanation again.
After the repeat, say the sentence back. This tests whether you heard the sounds and gives the tutor a chance to correct one point while it is still fresh.

Check meaning, spelling and sound separately
A learner can understand a word but not recognise its spelling, or read it while missing it in rapid speech. Name the problem. Use Beth mae hyn yn ei olygu? for meaning and Sut mae sillafu hynny? for spelling.
For pronunciation, point to the word and ask Sut mae ynganu hwn? - “How do you pronounce this?” Listen once without speaking, then imitate the whole word. On the next attempt, focus on the difficult sound rather than changing every syllable at once.
Record the answer as a short phrase. A bare dictionary form may change when it enters a sentence, and the phrase preserves useful grammar around it.

Make an uncertain answer easier to attempt
Dw i ddim yn siŵr, ond ... means “I am not sure, but ...”. That small opening lowers the emotional cost of trying. It tells the tutor you are thinking aloud rather than presenting a finished answer.
Give yourself a sentence stem. If the lesson is about opinions, begin with Dw i'n meddwl bod ... - “I think that ...”. If it is about preferences, use Mae'n well gen i ... - “I prefer ...”. A stable opening leaves more attention for the new vocabulary.
When corrected, repeat the improved version once. You do not need to apologise. A correction is information, not a judgement on whether you belong in the class.

Useful language for an online Welsh class
Technical problems need their own short phrases. Alla i ddim eich clywed chi means “I cannot hear you”, while Mae'r sain wedi torri communicates that the sound has broken up. If you lose connection, return and say Mae'n ddrwg gen i, collais i'r cysylltiad - “Sorry, I lost the connection”.
Use the chat for spelling, links and one-word checks, but do not let it replace speaking practice. If you type every answer first, the written form becomes a crutch. Give the spoken attempt, then use chat to confirm details.
Keep your microphone muted only when the class format requires it. Being ready to unmute promptly reduces the little delay that can make you withdraw from a turn.

Turn the phrases into automatic responses
- Write one classroom problem on the front of a card, such as “I missed the meaning”.
- Write Beth mae hyn yn ei olygu? on the back.
- Look at the problem and say the Welsh before checking.
- Practise two cards before each class for one week.
- Use a phrase in the real lesson even if English would feel quicker.
This works because the cue matches the future situation. You are not translating a random sentence. You are rehearsing a response to a moment that will return.
After class, mark the phrase you actually used. Real use is the strongest signal that the expression belongs in your active Welsh.
