To unscramble 'accelerate', start by identifying the letters: A, C, C, E, L, E, R, A, T, E. Next, look for common patterns or combinations. For example, 'ac' is a common prefix, and 'ate' is a common suffix. Try forming smaller words first, such as 'race', 'rate', 'tear', and 'care'. Once you have a list of smaller words, combine them to see if they can form larger words. Use a systematic approach by writing down different combinations and checking their validity.
