Read the FAQ explanation of Comprehensible InputReal Context
An English noun describing a soft-bodied invertebrate animal, often with a shell, such as a snail, clam, or octopus. The Mollusca are the large animal phylum that includes gastropods, bivalves, and cephalopods. Figuratively, mollusk can describe a person who is soft or easily influenced (informal), though this usage is not common in formal writing. In biology, mollusks typically have a muscular foot, a visceral mass, and a mantle, and many species produce shells. The word derives from Latin mollis 'soft', via mollusca and French mollusque, into English mollusk; spelling mollusks is common in American English, molluscs in other varieties.
Usage Reminders
- - Mollusk is countable: one mollusk, several mollusks.
- - Don’t confuse with molluscs; spelling varies by region.
- - Use the scientific sense in formal writing.
- - The informal figurative sense is rare and slightly negative.
- - Remember related terms: Gastropoda, Bivalvia, Cephalopoda.
Common Misconceptions
- Mollusk = shellfish; not all mollusks have shells
- All mollusks are soft and slow; some are fast movers like octopuses
- Mollusk is a fish; it is not a fish, it is an invertebrate
- The figurative use means someone is weak; it is informal and rare
- Mollusk vs molluscs: both are correct; regional spelling differences
Thinking Differences
Explain to an English speaker: English treats mollusk as a broad biological category; avoid assuming all examples are slow or that the word only refers to shellfish. The informal sense is infrequent and carries a light negative tone.
