Covered with dust or containing a lot of dust; dry and powdery in appearance or texture.
From 'dust' plus the suffix '-y' (meaning 'full of' or 'resembling'). 'Dust' comes from Old English 'dust,' possibly from Proto-Germanic roots related to 'powder' or 'to rise up.'
The word 'dust' appears almost identically in Germanic languages because it describes something so fundamental—the fine particles that rise from the ground whenever wind blows—that the word barely changed as languages evolved apart.
