Yesterday, a Bizarro with an ambiguity in auto parts. Today, another ambiguity, somewhat simpler than that one:
Two interpretations for the N + N compound bird seed, differing in the semantic relationship between the head N seed and the accompanying N bird — one like parrot seed ‘seed to give parrots, to feed parrots’, one like grass seed ‘seed of grass, i.e., of the grass plant; seed to grow grass from’.
