propriety - correctness
The formal word ‘propriety’ refers to conduct, speech, or actions that are considered socially or morally acceptable. People who behave in such a way tend to be self-restrained and care very much about doing the right thing, occasionally even to an excessive degree. However, they are looked upon favourably by society as a whole. The direct opposite of this is ‘impropriety’.
