Kangaroo word

A kangaroo word is a word that contains all the letters of one of its synonyms, called a "joey" word, arranged so that these letters appear in the same order in both words. For example, the word "action" is a kangaroo word containing the joey word "act"; the words "in[flammable]" and "[malign]ant" also each include their own synonyms. In the kangaroo word, the letters of the joey word may also be separated, as in "[ma]scu[l]in[e]", which contains the letters of "male" scattered throughout. Some compilers in fact require that the letters of the joey word not be consecutive within the kangaroo word, or may stipulate that the kangaroo and joey words be etymologically unrelated, so that in both cases words such as "action" (act), "inflammable" (flammable) and "malignant" (malign) would not qualify.
Kangaroo words were originally popularized as a word game by Ben O'Dell in an article for "The American Magazine", volume 151, during the 1950s, later reprinted in "Reader's Digest".
The phrase "kangaroo word" is derived from the fact that kangaroos carry their young, known as joeys, in a body pouch. Likewise, "kangaroo words" carry their "joey words" within themselves. A "twin kangaroo" is a kangaroo word that contains two joey words (for example: "container" features both "tin" and "can"). In contrast, an "anti-kangaroo" word is a word that contains its antonym (for example: "covert" carries "overt", "animosity" carries "amity"). A "grand kangaroo" is a kangaroo word which has two joeys, one of which is in the pouch of the other. For instance, "alone" is a grand kangaroo since it contains "lone", which carries its own synonym "one".
