The term 'obsessed with' can be expressed in four different ways: INTO, TAKEN, DEEPINTO, and HOOKEDON. INTO is a four-letter word that means to enter or become involved in something. TAKEN is a five-letter word that means to be captivated or attracted by something. DEEPINTO is an eight-letter word that means to be deeply involved in something. Finally, HOOKEDON is an eight-letter word that means to be strongly attracted to something. All of these words describe the same concept: being so focused on something that it becomes an obsession.
