Here is a sentence from a very good grammar book: "Hawkins was not, strictly speaking, a traitor." That sentence means: the word "traitor" is not really the correct word to describe Hawkins. That is, Hawkins's actions did not fit the legal definition of "traitor." ***** When you get time, go on the Web and search for "Style Disjuncts."

"Technically speaking", "strictly speaking" and "according to the facts..." all mean the same thing. They imply that what you are about to say is not your opinion but a universally accepted truth or general consensus. The phrases "technically speaking" and "strictly speaking" are usually used before saying something pedantic.
