Combination of two words, where the first letter(s) of the first word is joined with the second word minus it's first letter(s). Based on the "Portmanteau".

Subject to rules/preferences.

1) If the first word starts with a vowel, a compound word is not possible.
2) The user can include only the first letter of the first word, or a string of letters leading up to the first vowel of the first word.
Ex. Street + Nuts = Suts, Stuts, or Struts.
3) The user can include only the first letter of the second word, or a string of letters leading up to the first vowel of the second word.
Ex. Super + Glue = Sue, or Slue.

There are two main mutually exclusive categories.

A "Prodrome" is itself an existing word, but by sound, not spelling.

Ex. Tall + Boy = Toy.
Ex. Man + Juice = Muice (sounds like Moose, therefore a Prodrome).
Ex. Cell + Phone = Cone (a word by spelling, but not when pronounced with a soft "C", therefore not a Prodrome).

A "Callidrome" is itself not an existing word by sound, spelling is irrelevant.

Ex. Fucking + Cunt = Funt.
Ex. Small + Pear = Sear (a word by spelling, but not when pronounced to rhyme with pear, therefore a Callidrome).

There are 3 sub-categories, not necessarily mutually exclusive of each other.

A "Synondrome" sounds identical to the second word.

Ex. Dirty + Dick = Dick.

An "Antidrome" sounds identical to the first word.
Ex. Cock + Block = Cock.

A "Collidodrome" keeps the entire second word.
Ex. Fat + Ass = Fass.

Get the Compound Word mug.
Any object or thing that has two words in it. Only if you are playing Catch Phrase and/or you are drunk.
"Guys this is a compound word," as said by Chantel refering to the word Migrate framer in a game of Catch Phrase.
