# FOSS FOSS ([Free](free_software.md) and [Open Source](open_source.md) Software, sometimes also [FLOSS](floss.md), adding *Libre*), is a kind of neutral term for software that is both free as in freedom and open source. It's just another term for this kind of software, as if there weren't enough of them :) People normally use this to stay neutral, to appeal to both free and open source camps or if they simply need a short term not requiring much typing.
