The meaning of the word 'nugget'

So, I have been asked to clarify something...
'Chicken nugget' is a fairly broad term used to describe a breaded or battered piece of chicken (or chicken like product in vegetarian cases), in a variety of shapes, most notably:

• The dipper

• The boot

• The ball

• The goujon

• Popcorn chicken (some argue this isn't a nugget, I prefer to call it a 'nugglette')

Thus, I will use all of these terms to mean chicken nuggets, specifically 'dipper' as these are my preferred type of nugget!

Thanks for reading!
