Morphology
Avena + sterilis
The element 'Avena' clearly signals the oat genus, so a learner who knows that word would infer this is a kind of oat. However 'sterilis' is not a common English word (and scientific Latin epithets are labels rather than compositional descriptions), so the precise sense 'wild Mediterranean species believed to be the ancestor of cultivated oats' is not derivable from the parts, giving only partial predictability.
Etymology
Avena sterilis comes from Latin words: Avena means 'oat' and sterilis means 'barren' or 'not producing many seeds'. It is a wild Mediterranean oat thought to be the ancestor of the oats we grow today, so the name helps you remember it is the wild, earlier form of farmed oats.
