<p>Was wondering if someone could help. I am just about getting to grips with cateogry theory and adjoints. I have a query though, reading through some material.</p> <p>Does the forgetful functor from the category Group of groups to Set have a left adjoint?</p>

Wow quick! Thanks! I need to start proving these types of questions. Do you know where I could get a model proof for this? It would be great to see a perfect answer before I try to do similar on other functors :)
