"Article on" vs "article about"
Which one is correct: an excellent article on ant behaviour or an excellent article about ant behaviour?
If both are correct, is there a difference in their meaning and usage?
Solution 1:
Both correct.
Difference in usage is very subtle.
On would be a preference in many contexts. On is probably more common in spoken and written language, but I believe about might be a little more common in spoken language than it might be in written language.
