'Infix' is a grammatical term that refers to a word element that is added to the middle of a word to change its meaning. For example, in the word 'unbelievable', the infix is 'liev' which is added between 'be' and 'able'. Another example is in the word 'fan-freaking-tastic', where 'freaking' is an infix added between 'fan' and 'tastic' to add emphasis or emotion. Infixes are not commonly used in English, but knowing about them can be helpful in understanding certain words and their meanings. They are mostly used in informal language or slang.
