mimeograph, copy
謄 centers on making an exact duplicate: copying a document or reproducing it by mimeograph. The idea is faithful reproduction rather than original creation.
謄 combines 言 (words, speech) with a phonetic component that historically relates to rising or copying. The exact origin of the right side is uncertain, but the character likely expresses copying written words.
The left side 言 represents words or text. The right side looks like a stack of papers being duplicated. Together, 謄 means copying text onto multiple sheets.
For トウ, imagine a copying machine that makes a toe-shaped stamp on every page: toe -> トウ, and each copy gets the same toe mark.
