A good RAG answer isn't about sounding polished — it's about speaking only in words you can actually point to on the page.
Let's think about it this way for a second
"Grounded" just means your feet are still on the ground — every fact in the answer needs to actually appear in the chunk you just read. If it doesn't, say "not found in the text." It's the same as a teacher asking "where exactly does the book say that?" A short answer with a quote is more trustworthy than an elegant sentence. Never tell the model to "fill in something nice if you're not sure."
Let's connect it to everyday life
Say the chunk reads "Phones must be off during class." A good answer: "According to the document, you can't use it during class." A bad answer: "If the teacher allows it, you could take notes on 5G." The second one sounds nice, but none of it is actually in the text. Write "only use the notes below" into your prompt, then double-check the answer against the source yourself.
Let's try it hands-on together
Notes:
စာသင်ချိန်မှာ ဖုန်းပိတ်ရမည်
Good: စာအရ စာသင်ချိန်မှာ ဖုန်းမသုံးရပါ။
Bad: ခေတ်မီကျောင်းများတွင် tablet ကို အသုံးပြုနိုင်သည်။You'll be able to tell a grounded answer apart from a guessed one.5-Minute Try-It
Write a short chunk. Compare a correct answer against a polished-but-wrong one.
One Quick Warning
Confident tone is a trap. RAG can state something firmly and still not match what the document actually says.
