Morphology

roseola + infantum

The compound pairs 'roseola' (a viral rash) with the Latin element 'infantum' signaling relation to infants, so the overall meaning (‘roseola affecting infants’) is largely compositional. However, the second element is a Latin inflection rather than plain English and the phrase is a technical medical term, so a B1 learner—even knowing the parts—may not fully recognise the genitive/relational form; this partial predictability makes it only semi-transparent.

Etymology

The name roseola infantum comes from old words: roseola meaning 'little rose' and infantum meaning 'baby'. The illness is named for the pale pink 'rash' that appears in young children after a high 'fever', so the name helps you remember this childhood illness.
