The crossword solutions for the term 'break, as a habit' are 'UNLEARN' and 'therein'. Unlearning is the process of undoing or reversing a learned behavior or habit. It is an important part of breaking a habit, as it involves actively removing the learned behavior from one's life. Therein refers to the idea that the process of unlearning must be done within oneself, as it is an internal process. Therefore, the two crossword solutions together suggest that in order to break a habit, one must first UNLEARN it within themselves.
