Morphology

pin + grass

The noun 'grass' makes it clear to a B1 learner that this refers to a kind of plant, and the modifier 'pin' plausibly suggests a small or pointed quality, so learners can infer it is a type of grass. However, the precise botanical identity and the specific features in the definition (reddish stems, fernlike leaves, forage use) are not predictable from the constituents alone, so the phrase is only partially transparent.

Etymology

The name pin grass may come from the plant's thin, upright seed parts that look like little pins sticking up from the grass. So, the name now refers to a common 'weed' people use as 'forage' for animals.
