Qual è la differenza tra speciality e specialisation ?Sentiti libero di rispondere con un esempio.

Speciality is something that someone is good at, better than anyone else.

For example, to say that Putin is good at politics, you can say:
Politics is Putin’s speciality.

Specialisation: the best way to think about it, is that in a list of many things, specialisation is just ONE part of all of the things.

For example, when you describe Putin’s character you can say:

Mr Putin is good at golfing, hunting, fishing and politics. But politics is his specialisation.

So to summarise: Speciality is when you are describing one thing and saying it is someone’s speciality. But specialisation is when you are describing a group of things, and then one of those things is the best of them all so you say that it is the specialisation.
