Let´s avoid needless words

It seems that Emerson answered Thoreau´s "Simplify, Simplify" by saying that one Simplify was enough. And he was right.
Let's take a peek at needless words:

Lift up – “Can you lift the chair?”

Listen up – “This is important. Listen.”

Make perfectly clear – “Let me make it clear.”

Mix together – “He mixes with lowlife people.”

May possibly – “It may happen.”

Never before – “I have never done a thing like that.”

Might possibly – “He might come.”

None at all – “None came to the party.”

New recruit – “This is our recruit.”

Open up – “I refused to open the door.”
