- tufftuff → tauftauf
- Joyce's letter to Harriet Shaw Weaver of 15 November 1926: "Tauf = baptise (German)"
- taufen: (German) to baptise
- teuf-teuf: "Well, teuf-teuf," I said moodily and withdrew. (P.G. Wodehouse: Very Good Jeeves: The Love That Purifies, 1930); "Teuf-teuf" in French means the sound of a train ("töff töff" in my native German). Obviously "teuf-teuf" was a common phrase in Edwardian upperclass slang. So it suggests "I'll be gone, bye-bye" or something like that.
- mishe mishe to tauftauf: "me me to thou thou"
- tau, tau: (Greek) T, T → Tris-tram/Tram-tris, Tris-tan/Tan-tris, etc.
