Root Explanation

Pitchblende → The word 'pitchblende' is derived from 'pitch' (from Middle English *picche*, meaning a thick, black substance) and 'blende' (from German *Blende*, meaning to deceive or to mislead, referring to the mineral's deceptive appearance). The term describes a mineral that appears different from what it actually is, particularly in its uranium content.

Memory Tip

Think of 'pitch' as a thick, dark substance and 'blende' as something that can mislead you about its true nature. This helps you remember that pitchblende is a mineral that can appear different than it really is.
