Many English number-names can be imbedded in words or split between two words; Martin Gardner exploited the latter idea in a Kickshaws quiz. Alternatively, the sounds of number-names can be embedded.

The following summary of Czech number-words was translated by Harry Partridge of Manhattan Beach, CA.
