A neologism coined by Röandil on 2023-02-24 in the Vinyë Lambengolmor Discord Server (VLDS) inspired by S. sant “garden, field, yard” (VT42/20). He also proposed the following ideom: santa-[personal possessive X]-sse “for [X]’s part; as far as [X] is concerned; from [X]’s point of view; as comes from/is done by [X]” (lit. “in [X]’s garden”). Personally I prefer to retain ᴱQ. tarwa for “garden”.
