Some people use 'addicting game' and others use 'addictive drugs' - What's the proper usage?
The meanings reported by the NOAD for addictive are:
- (of a substance, thing, or activity) causing or likely to cause someone to become addicted to it
- of, relating to, or susceptible to being or becoming addicted to something
Addicting is, as the dictionary reports, the informal equivalent of addictive.
Both addictive and addicting are correct; only the context where the word is used changes.
Addict is a noun that means "a person who is addicted to a particular substance, typically an illegal drug." Its etymology is early 20th century, from the obsolete verb addict, which was a back-formation from addicted.
As it is associated with gaming I suggest that the use of
addicting is incorrect, probably introduced by children who haven't learnt enough yet, because they spend too much time playing video games and not enough time learning to speak.
The suffix determines the meaning of the word and in this case Martin Becket is without a shadow of a doubt correct.
