Which symbol type has no relationship between symbol and referent and must be learned?

• A. Symbolic
• B. Transparent
• C. Opaque
• D. Translucent

Answer: (C)

When signs vary in how closely their form hints at what they mean, you can have clear cues, partial cues, or none at all. Signs with no visible link to their referent rely entirely on learned conventions; you must memorize what each form stands for because there’s no clue in its appearance. That’s what the term opaque captures: no perceptual relationship to what it represents, and the association must be learned. In contrast, a sign that looks like what it means (transparent) gives you an easy, immediate clue, and a sign with only partial hints (translucent) isn’t as straightforward.
