Morphology

Down + syndrome

The word 'syndrome' transparently signals a medical condition (a set of symptoms), so a learner who knows 'syndrome' will infer this is a health-related term; however 'Down' here is a proper name (not the directional/adverbial meaning) and gives no semantic clue to the genetic cause or characteristic features. Because part of the meaning (that it is a medical condition) is clear from the constituents but the crucial specifics are not derivable, the expression is best classified as semi-transparent.

Etymology

Down syndrome is named after the British doctor John Langdon Down, who first described the condition in the 1800s. It refers to people 'born with an extra copy of chromosome 21', which can lead to certain physical features and learning differences.
