Etymology
the word 'pearly' is a straightforward english derivation. its base, 'pearl', entered english from the old french 'perle', which itself likely derived from the vulgar latin 'pernula', a diminutive of latin 'perna' meaning 'mussel' or 'ham', referencing the shape of the shellfish. the adjectival suffix '-y', of old english origin, is one of the language's most productive means for forming descriptive terms. thus, 'pearly' literally means "having the qualities of a pearl," a logic that has remained transparent from its formation to its modern use describing lustrous, iridescent, or pearl-like appearances.
Analysis
pearl (from latin 'perna', meaning mussel, via old french 'perle', meaning pearl) + y (old english '-ig', an adjective-forming suffix meaning "characterized by; full of; resembling").
