Let’s deconstruct an example from the great Winston Churchill. All the power words are underlined:
We have before us an<u> ordeal</u> of the most <u>grievous</u> kind. We have before us many, many long months of <u>struggle</u> and of <u>suffering</u>. You ask, what is our policy? I can say: It is to wage <u>war</u>, by sea, land and air, with all our <u>might</u> and with all the<u> strength </u>that God can give us; to wage<u> war against </u>a monstrous tyranny, never <u>surpassed</u> in the dark, lamentable catalogue of<u> human crime</u>. That is our <u>policy</u>. You ask, what is our<u> aim?</u> I can answer in one word: It is <u>victory, </u>victory at all costs, victory in spite of all<u> terror, victory</u>, however long and hard the road may be; for without victory, there is no <u>survival.
