“layt” → could be “that”? l→t? a→h? y→a? t→t? Not matching well.
Without more clues, I can’t decode it fully, but the cipher looks like a or a polyalphabetic cipher with a short key like “solid” or “paper”. danlwd nt wy py an layt ba lynk mstqym
danlwd → dwlnad nt → tn wy → yw py → yp an → na layt → tyal ba → ab lynk → knyl mstqym → myqtsm “layt” → could be “that”
“dan lwd” in Welsh? “dan” = under, “lwd” not standard. “nt” = not English Welsh. “wy” = Welsh for “is” (third person present of ‘bod’? Actually, “wy” = they, but mutation). “py” not Welsh. “an” = Welsh for “from”/”of”. “layt” not Welsh. “ba” = Welsh “if”/”would”. “lynk” = link? “mstqym” no. Without more clues, I can’t decode it fully,
But “nt” ROT13 → “ag” not a word. So maybe not ROT13.
Let me check possible ciphers.
