Danlwd Nt Wy Py An Layt Ba Lynk Mstqym Access

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”.

“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.

Given that “solid paper” is the title, maybe the ciphertext decodes to something like: or similar.

Need a key. Common keys: “solid”, “paper”. Try “solid” on first word danlwd: d(3) – s(18) = (3-18 mod 26) = -15 mod26 = 11=L a(0)-o(14) = -14=12=M n(13)-l(11)=2=C l(11)-i(8)=3=D w(22)-d(3)=19=T d(3)-? key length 5, 6th letter use s again: d(3)-s(18)=11=L → LMCDTL → no.

If I must guess based on typical puzzle answers, the decoded phrase could be: (word lengths 4,2,1,6,2,1,5,2,5,6) — but our ciphertext has 5,2,2,2,2,4,2,4,7 — mismatched.

But apply Atbash to whole string with spaces ignored then regroup: d→w, a→z, n→m, l→o, w→d, d→w → “wzmodw” n→m, t→g → “mg” w→d, y→b → “db” p→k, y→b → “kb” a→z, n→m → “zm” l→o, a→z, y→b, t→g → “ozbg” b→y, a→z → “yz” l→o, y→b, n→m, k→p → “obmp” m→n, s→h, t→g, q→j, y→b, m→n → “nhgjbn”

“layt” → could be “that”? l→t? a→h? y→a? t→t? Not matching well.
