Puppies are very smart and learn things quickly and easily. With human babies we label everything to help the child understand their world and to communicate with them. We can do the same with puppies.
Whenever you are interacting with your puppy talk to her the whole time. Label things and actions. Puppies need to know what things are so they are not afraid of them later on. If you give something a label you can tell her what it is and she will know what you are talking about. When feeding your puppy tell her it is time to eat. Afterwards ask if she needs a drink. Give all of her toys a label. When she is playing with something say the name of the toy. Later on you can ask her to go get a certain toy. Outside tell her what everything is that she sees and is interested in. Label both pee and poop instead of just potty so if she does one you can ask her to do another. Teach her everyone's names so that you can tell her who is coming to visit. If you have other pets she should know who they are too.
Being able to communicate with your dog allows you to enjoy your pet more and strengthens the bond between you and your best friend.
