The term 'changed for the better' can be expressed in three different ways: emended (7 letters), AMENDED (7 letters), and reformed (8 letters). Emended means to make minor corrections or revisions to a text, while AMENDED means to make changes or additions to a law or document. Reformed, on the other hand, means to make significant changes to an existing system or structure. All three terms imply that something has been improved or altered in a positive way.
