In the play-within-a-play, Tom Snout plays the wall which separates Pyramus' and Thisbe's gardens. In Pyramus and Thisbe, the two lovers whisper to each other through Snout's fingers (representing a gap in the wall). Snout has eight lines under the name of Tom Snout, and two lines as The Wall. He is the Wall for Act V-Scene 1.
Tom Snout was originally set to play Pyramus's father, but the need for a wall was greater, so he discharged The Wall. Snout is often portrayed as a reluctant actor and very frightened, but the other mechanicals (except Nick Bottom and Peter Quince) are usually much more frightened than Tom Snout).
Snout's name, like that of the other mechanicals, is a metonym and derives from his craft: "Snout" means a nozzle or a spout, a feature of the kettles a tinker often mends.[2]
