Morphology
Delichon + urbica
This is a Latin binomial (genus + species) where the parts function as taxonomic labels rather than ordinary compositional English words; 'Delichon' and the unattested 'urbica' do not form a predictable everyday meaning for a B1 learner. Even though 'urbica' resembles the root of 'urban', the scientific name requires specific biological knowledge and is not transparently derivable from its constituents, so learners would not infer 'house martin' from the parts alone.
Etymology
Delichon urbica: the first part Delichon may come from an old word for a small swallow, and the Latin part urbica means 'of the town'. The name gives a clear image — a small swallow that lives on houses and nests under the roof edges, which is why we call it the 'house martin'.
