orpiment
C2Technical, Literary, Historical
Definition
Meaning
A bright yellow mineral composed of arsenic trisulfide, historically used as a pigment and in medicine.
In extended use, it can refer to anything resembling this mineral in colour or context, and serves as a historical example of a toxic pigment used in art.
Linguistics
Semantic Notes
The term is highly specific and denotes both a specific chemical compound (As2S3) and its historical applications. Its usage outside mineralogy, art history, or historical texts is exceptionally rare.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage. Spelling is identical.
Connotations
Both varieties carry the same connotations of antiquity, toxicity, and a specific bright yellow hue.
Frequency
Equally rare in both dialects, confined to specialised fields.

Learning
Memory Aids
Mnemonic
Imagine an OLD PIGMENT (sounds like 'orpiment') that artists used, but it was made of poisonous ARSENIC. 'Or' for 'ore' (mineral) + 'pigment'.
Conceptual Metaphor
[Not commonly metaphorized due to extreme specificity. Possible conceptual link: 'A bright but deceptive/harmful thing' (due to its toxicity).]
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'аурипигмент' (the direct equivalent) or simpler terms like 'жёлтый мышьяк' (yellow arsenic). The English term is a direct borrowing from Latin via French.
Common Mistakes
- Mispronouncing as 'or-pie-ment' /ɔːrˈpaɪmənt/.
- Confusing it with 'realgar' (another arsenic sulfide mineral which is red).
- Using it as a general term for any yellow colour.

FAQ
Frequently Asked Questions
No, due to its high toxicity (arsenic content), it has been replaced by safer modern pigments like cadmium yellow or arylide yellow.
It is characteristically a bright, lemon yellow colour.
It derives from the Latin 'auripigmentum', meaning 'golden pigment' (aurum = gold, pigmentum = pigment).
No. As an arsenic compound, it is poisonous if ingested, and dust from it can be hazardous if inhaled. It should only be handled with appropriate safety precautions in a controlled setting.
