Psychotropic

/ˌsaɪkoʊˈtroʊpɪk/adjective

Of a drug that acts on the brain to alter mood, perception or behaviour.

The Greek roots

ψυχή
psychḗ
breath, soul, mind
+
τρέπω
trépō
to turn, redirect

Literally: mind-turning

The story of the word

ψυχή plus τρέπω, to turn: something that turns the mind. The word entered English in the 1950s, exactly when chlorpromazine and the first antidepressants were emptying the back wards of asylums, and it names the whole class without judging it. That same τρέπω gives heliotrope, the plant that turns toward the sun, and entropy, Clausius's 1865 coinage for energy turning toward disorder.
