Intervening is a term that can be used to describe something that is located BETWEEN two other things. The term can be broken down into several different words, such as INTERIM (7 letters), INTERMEDIATE (12 letters), CENTRAL (7 letters), BETWEEN (7 letters), and MIDDLE (6 letters). Each of these words can be used to describe something that is located in the MIDDLE of two other things. For example, an INTERIM solution could be used to describe a temporary solution to a problem, while an INTERMEDIATE solution could be used to describe a more permanent solution. CENTRAL and BETWEEN can both be used to describe something that is located in the MIDDLE of two other things, while MIDDLE can be used to describe something that is located in the exact center of two other things.
