Q: Can Synonyms be imported into the SharePoint Term Store?


The SharePoint term store CSV import format does not allow you to import synonyms.
A workaround for this can be to add synonyms next to the term name in the import file. Then, after you have imported the file, you can simply cut and paste the synonyms from the term name over to the Other Label field in SharePoint. While this is not ideal, it may be easier than manually typing in each synonym.
Some third party add-ons have their own import format which do allow for import of synonyms into the term store.
