In a very bad or severe way; to a great degree.
The weather was awfully cold during our trip.
Awfully is formed from "awful" (from Old English "aweful", meaning full of awe or fear) and the suffix "-ly" (meaning in a manner of). The word "awfully" means in a manner that inspires awe or fear, often used to intensify a negative quality.
Think of something that is 'full of awe' ('awful') and how it can be described 'in a manner' ('-ly'). This helps you remember that 'awfully' describes something done in a way that inspires strong feelings.
