Symbiotic stars are long-period interacting binaries composed of an evolved giant and a hot compact companion. Their rich and complex optical spectra make spectroscopy indispensable for identifying new systems, characterising their stellar components and orbital motion, and probing the physics of accretion and outbursts. In the time domain, spectroscopic monitoring provides unique diagnostics of activity, many of which cannot be detected with photometric data alone. Spectroscopic surveys are therefore crucial to uncovering the true population and diversity of symbiotic binaries. Looking ahead, facilities such as the Wide-field Spectroscopic Telescope promise a transformational leap, enabling systematic discovery of Galactic and extragalactic systems, and long-term spectroscopic monitoring on an unprecedented scale. In my contribution, I will highlight how optical spectroscopy shapes our current understanding of symbiotic binaries and the prospects opened by next-generation spectroscopic facilities.
