Any state of unresponsiveness, indifference, or failure to turn towards or react to an influence, often used figuratively in non-biological contexts to describe social or psychological detachment.
Linguistics
Semantic Notes
Primarily used in botany and biology. The figurative extension is rare and typically found in highly specialized academic or literary prose. Not to be confused with 'atrophy' (wasting away) despite phonetic similarity.

Learning
Memory Aids
Mnemonic
Think: 'A-tropism' as in 'Away from any turning' or 'Absence of turning'. Link 'atro-' to 'atrophy' (a wasting away, also a lack of growth) but remember it's about direction, not size.
Conceptual Metaphor
INDIFFERENCE IS A LACK OF TURNING (e.g., 'His atropism to the criticism was notable.').

Common Pitfalls
Translation Traps (for Russian speakers)

Common Mistakes
- Using 'atropism' to mean 'atrophy'.
- Spelling as 'atrophism' or 'autropism'.

No, it is a very low-frequency, technical term specific to biological sciences.
The general opposite is 'tropism' (directional growth response). Specific opposites include phototropism (response to light) or geotropism (response to gravity).
