The term "dis-tending" refers to the process of making something larger or expanding it. The opposite of dis-tending would be to make something smaller or contract it. Some antonyms for dis-tending include compressing, constricting, contracting, shrinking, and reducing. These terms describe the process of bringing something together or making it smaller in size. For example, if a balloon is dis-tended, it is being blown up and made larger. Conversely, if a balloon is compressed, it is being deflated and made smaller. As such, antonyms for dis-tending describe the opposite process of making something smaller or reducing its size.
