I’ve been wondering, can I use “in association with” in the following way:
#1 He did research into the subject matter in association with his professor.
#2 The crime is being investigated by a private eye in association with the local police.
By “in association with” I mean “with the help from”.
To my mind ‘in association with’ does indeed suggest ‘with help from’ but I would use it more with reference to organisations, bodies, authorities and so on. For that reason
seems appropriate. In your first sentence
you are talking about an individual (the professor) and in that case I would use ‘in collaboration with’.
Many thanks for your thorough explanation,
now it’s all clear to me!
