Entreprendre: It's a verb that had given us the word entrepreneur with all its many connotations of business success. It is reported that George Bush once complained that the problem with the French is that they don't have a word for entrepreneur although the truth of this statement is contested here. The noun has come to mean many things since it was first coined back in the early 18 century. See Wikipedia article here
I like the French verb entreprendre. It breaks nicely into two parts, between and to take. To take between.
For middle leaders, managing their teams and being managed themselves the verb seems appropriate. Taking between.
Does that make middle leaders/managers entrepreneurs?
