Is there any difference between these two sentences: 'What do you think of him?' and 'What do you think about him?‘
Thank you for your help.
In general, when you "think of something" you come up with an original idea but when you "think about something" you are remembering or considering aspects of a thing.
Therefore 'What do you think of him?' would be a question that you ask someone who has met 'him' for the first time (e.g. a first impression), whereas 'What do you think about him?‘ is asking for a more detailed and considered response.
