Opinion of, Opinion on, Opinion about
A reader objected to the use of “on” in an example given in a post about prepositions:
REFERENCE: He asked my opinion on the matter. IMHO, I think this use is a stretch. I would substitute “about” for “on.” “He asked my opinion about the matter.” More and more it seems that writers have forgotten the word “about” and use “on” instead, a rather annoying tendency.
According to an informal web search using quotation marks around the phrases, opinion of is more common than either opinion on or opinion about:
“opinion about” 7,470,000 hits
“opinion on” 18,600,000 hits
“opinion of” 52,800,000 hits
The OED entry for opinion reflects this apparent preference, offering one example each for “opinion on” and “opinion about,” but 24 for “opinion of.”
All three sound fine to me.
Here are some quotations from newspapers:
Looking for political cover, Senate Majority Leader Mitch McConnell, R-Ky., said Tuesday, “Everybody I know in the Senate, everybody is in favor of maintaining coverage for pre-existing conditions. There is no difference of opinion about that whatsoever.”
Expert opinion on game-related research is further split, with hundreds of academics calling findings linking playing video games to violence flawed, while others argue that studies show “either no relationship between playing video games and violent behavior, or an ‘insignificant’ link between the two.”
