This module generates content for all foreign derivation templates that support multiple comma-separated sources, in the specific case where more than one source is specified. The code for this use case is placed in its own module to save memory in the common case where only a single source is used. The current (as of June 2022) templates that support multiple sources are {{borrowed}}/{{bor}}, {{derived}}/{{der}}, {{cognate}}/{{cog}}, {{noncognate}}/{{noncog}}, and all the specialized borrowing templates:

• {{learned borrowing}}
• {{semi-learned borrowing}}
• {{orthographic borrowing}}
• {{unadapted borrowing}}
• {{calque}}
• {{partial calque}}
• {{semantic loan}}
• {{phono-semantic matching}}
• {{transliteration}}
