Q: What are the definitions of a thrombus and a blood clot (Danish: Koagel)?

There seems to be some confusion amongst the different books and teachers regarding the definitions of a thrombus and a blood clot (Danish: Koagel).

Can someone please define:
1) What is a clot, what is it made of and when does it form?
2) What is a thrombus, what is it made of and when does it form?
3) Do thrombi only form under pathological circumstances?
