Marinated Pork Chops

I have often been mystified by the difference in marinade and marinate.  Which one is supposed to be used?  I know it depends on the situation, but that’s as far as my knowledge really goes.  For the sake of trying to be correct, I looked it up.  Here is what I found:  Marinade is the physical stuff that meat or other things are put in, whereas marinate is the verb or action of having meat in a marinade.  I only think I fully understand, I hope I have the correct version in my title… 

Ingredients:

2/3 cup oil

1/3 cup soy sauce

1/4 cup cider or red wine vinegar

2 tbsp lemon juice

2 tbsp Worcestershire sauce

2 cloves garlic minced

1-2 tbsp dry mustard

1-2 tsp course black pepper

1 tsp salt

6-8 boneless pork chops

Mix first nine ingredients in a medium bowl and place in a re-sealable plastic bag.  Add pork, turn to coat, seal and refrigerate over night.  Place chops on a medium hot grill and cook until internal temperature reaches 165 to 170 F.  Remove from grill and let rest 5 minutes.  Serve.
