If you have some level of redundancy in your terms, it may be time to merge them. You may need to merge terms if you are retiring one product and replacing it with a similar product or if you have duplicative terms that refer to the same concept. In either case, merging terms may be the solution:

1. Expand the groups and navigate to the term set that contains the term you want to collapse into another. 

2. Point to the item you wish to collapse or merge into another, click the down arrow that appears next to it, and then select Merge Terms. In the following example, the Time Off term is going to be merged into the Time Away term:
   

3. On the Select term to merge into page, select the target term and click OK.
4. Acknowledge the dialog box regarding the term merge. The synonyms, translations, and other properties of the source term will be copied into the target term. Click OK to continue the merge or Cancel to abort.
5. Click Save to save the updated term.
