Surface Forms
Morphology
nucleoside = nucleus (opaque) = nucleo + oside
Formation involves the combining form 'nucleo-' and the specialized chemical suffix '-oside' (not the common word 'side'), so ordinary learners cannot derive the specific biochemical meaning.
Etymology
Nucleoside comes from nucle-, the same root as nucleus meaning 'core' or 'kernel', plus the part -oside, which is used in words for sugar compounds. So a nucleoside is like a 'core' base joined to a sugar, which explains why it is a base plus sugar but has no phosphate group.
