Morphology
The compound is a straightforward noun–noun name: 'thistle' names the plant and 'boar' simply specifies a variety or association, so a learner who knows both words will infer it denotes a type of thistle. This follows common cross‑linguistic patterns for plant names (e.g. 'goat willow', 'oxeye daisy') and contains no idiomatic shift, making the meaning transparent.
Etymology
Boar thistle likely comes from the simple picture of a boar (a 'wild pig') near a thistle plant. One popular idea is that boars would dig for food near these tough, prickly plants, or the sharp leaves might catch on a boar's hair, so people linked the animal and the plant. That's why boar thistle refers to a large, prickly weed.
