Foreshadowing is the warning or indication of an event that is to happen in the future. Some foreshadowing may appear almost too subtle to notice, while others may be completely obvious. George Bernard Shaw uses foreshadowing throughout Pygmalion to hint at what is to come. From subtly using a storm in Act 1 to suggest future conflict, to Higgins and Pickering joking about being able to turn a flower girl into a Duchess, which in itself is the entire plot; George Bernard Shaw loves the literary device of Foreshadowing.
