1945: I got into the bus full of taxpayers who were giving some money to a taxpayer who had on his taxpayer's stomach a little box which allowed the other taxpayers to continue their taxpayers' journeys. I noticed in this bus a taxpayer with a long taxpayer's neck and whose taxpayer's head bore a taxpayer's felt hat encircled by a plait the like of which no taxpayer ever wore before. Suddenly the said taxpayer peremptorily addressed a nearby taxpayer, complaining bitterly that he was purposely treading on his taxpayer's toes every time other taxpayers got on or off the taxpayers' bus. Then the angry taxpayer went and sat down in a seat for taxpayers which another taxpayer had just vacated. — Raymond Queneau, 'from Polyptotes' in Exercises in Style, 1945 (Eng. 1958)

On an indictment on the 12 Geo. 2, c. 26, s. 8, 31 Geo. 2, 32, s. 14, and 24 Geo. 3, c 53, s. 16, for removing from one silver kneebuckle to another silver kneebuckle certain stamps, marks, and impressions, to wit, the King's head and the lion rampant, with intent to defraud the King, against the statute, &c. ; on producing the silver kneebuckle in evidence, it appeared that the mark was a lion passant, instead of a lion rampant; and the Court held the variance fatal.

The purposive meaning desemanticizes and a new marker is drafted in to reinforce the purposive meaning.
