Extremely → It is formed from "ex-" (meaning out of or from) and "tremere" (meaning to tremble). The word "extremely" conveys the idea of something that causes a strong reaction or tremor, indicating a high degree or intensity.
Think of something that makes you 'tremble' ('tremere') because it is 'out of' the ordinary ('ex-'). This helps you remember that 'extremely' means very intense or high in degree.
