Morphology

Crocethia + alba

This is a Latin taxonomic binomial: 'Crocethia' denotes the genus (sanderlings) and 'alba' is a species epithet (commonly 'white' in Latin). If a learner knows the constituent elements, they can infer this refers to a species of Crocethia (i.e. a sanderling), so the meaning is compositional rather than idiomatic.

Etymology

Crocethia alba probably combines a word for 'sand' or 'shore' in Crocethia with alba, the Latin word for 'white'. So the name gives the image of a small white bird running along pale sand, which matches the 'sanderling'.
