Normality?

Normalcy?
As idiosyncrasy is a habit or peculiarity to one particular person. It means you do things that are unique and peculiar to you alone. Such as rolling your eyes when you talk.







Therefore the opposite would be standard, ordinary, typical, customary, common, average, natural, habitual, routine, conventional, regular.



This would imply you did things that were like everybody else. So while it would be an idiosyncrasy to roll your eyes when you talk. It would just be normal to talk ( as long as you were human)

Hi-



Well, "idiosyncrasy" falls under the definition of "Eccentric" - so I would say "conventional" would be the antonymn.





All the best,
