[Grammar] ‘concern for’ VS ‘concern about/over/with’

[northpath]

In a Longman Dictionary I read
concern for
▪ our concern for human rights
▪ The reforms are motivated by a concern for the disabled.
concern about/over/with
▪ the rise of concern about the environment
▪ the growing concern over inflation
▪ concern with worsening law and order
▪ I did voice my concern about the financial management

Not much information about how to discriminate these two cases. Is there a rule of thumb for that?

 

[jutfrank]

No, not really, but to keep it relatively simple, what I would advise is this:

• concern for something you think is at risk (concern for human rights)
• concern about something you think might put something else at risk (concern about global warming)
