Morphology
A learner who knows 'seed' (small particle) and 'lac' (natural resin) can infer that 'seed lac' refers to a small or granular form of lac, so the basic idea is compositional. However, the precise technical sense (made by crushing and washing stick lac and used in shellac production) is specialized and not fully predictable from the constituents alone, so it is only partially transparent.
Etymology
Seed lac comes from the small grain-like pieces made when workers crush and wash stick lac, the resin insects leave on tree branches. Because the pieces look like tiny 'seeds' and are the cleaned granules used to make 'shellac' and varnish, the name seed lac came to mean those small bits.
