Sometimes a phrase that sounds right and feels right is in fact wrong and this is known as an Eggcorn. It can be a word or a phrase that seems perfectly logical but is mistakenly used, for example “old wise tale” is sometimes used instead of “Old wives’ tale”. The term Eggcorn was coined by Geoffrey Pullum on the Language Log blog back in 2003 and has been used ever since. Linguistic expert RobWords takes a look at some of these mistakes and discusses other linguistic mishaps, including malapropisms, folk etymologies and mondegreens.
