Morphology
chlorosis = chlor (semi-transparent) = chlor + osis
The formation 'chlor-' (green) + '-osis' (condition) signals a problem with greenness/chlorophyll; learners familiar with 'chlorophyll' can infer it relates to leaf greening, though the actual symptom (yellowing) may be slightly counterintuitive.
Etymology
Chlorosis comes from the Greek word chloros 'green' and the ending -osis 'condition', the same root you see in chlorophyll which gives leaves their green color. So for plants, chlorosis means they lose their green color (their chlorophyll), which is why the leaves turn pale or yellow.
