The term Free Software is typically associated with software licensed under an FSF-approved license (The Free Software Definition), and the term Open Source (Software) is typically associated with software licensed under an OSI-approved license (The Open Source Definition).

Most of the applicable licenses are both, FSF- and OSI-approved. But there are exceptions. So

• not all Free Software is Open Source (Software),
• not all Open Source (Software) is Free Software.

Is there a term that includes both sets?

The alternative term FOSS, which stands for "free (and) open-source software", is, according to its Wikipedia article, for software that

can be classified as both free software and open-source software.

I guess that this applies also to FLOSS, which stands for "free/libre (and) open-source software".
