OTS-derived fonts are essentially fonts that are developed or modified based on the OpenType specification. The OpenType format, introduced by Adobe and Microsoft, is a widely adopted standard for font files. It allows for a single font file to contain multiple glyphs (characters, symbols, etc.) and provides support for advanced typographic features. OTS-derived fonts leverage this specification to create fonts that are highly versatile, compatible with various operating systems and applications, and capable of rendering high-quality text.
