The wordmonosyllabicisn’t one syllable , longis only four letters , lispis hard to pronounce if you have a list-processing language , andsynonymdoesn’t have any equivalent word . Or does it ?

The solution to that last question is a bit complicated . Thesaurus.comlistsmetonymas a synonym ofsynonym , but their signification are n’t exactly the same . The Oxford Dictionary of English Grammardefinessynonymas “ a Book or phrase that means the same , or almost the same , as another in the same lyric . ”Metonym , on the other hand , is defined as “ a word or expression which is used as a backup man for another word or face with which it is in a closelipped semantic kinship . ” For instance , the crowncan be used to refer to the king , andWashingtonsometimes refers to the U.S. government .

There is another theory , though : poecilonym . This is probably the closest equivalent word ofsynonym , although it ’s antiquated and rarely used .
