The term 'be familiar with' can be expressed in three different ways. The first is 'KNOW', which is a four letter word meaning to have information or understanding of something. The second is 'knowof', which is a six letter word meaning to have some knowledge or awareness of something. The third is 'knowwell', which is an eight letter word meaning to have a thorough understanding of something. All three words express the idea of being familiar with something, but the level of familiarity increases with each word.
