Where it sits
Rare and archaic, but real. It gets accused of being fake far more than it deserves.
Tell it apart
| Aspect | Psithurism | Susurration |
|---|---|---|
| Current use | No | Yes |
| Applies to | Trees only | Any murmur |
| In the OED | Yes | Yes |
| Understood | Rarely | Usually |
Near-synonyms with opposite practical value. Susurration is in current use and applies to any soft murmur; psithurism is obsolete and specifically arboreal. If you want to be understood rather than admired, use susurration.
What it doesn't mean
False — and this is the correction most needed here. It appears in the OED, Collins, Cambridge, Dictionary.com and Wiktionary. It's archaic and rare, but genuinely lexicalised, and it predates the internet by well over a century.
The Greek root psíthuros also means slanderous or whispering — the same word family gives the sense of furtive gossip. The word's ancestry is closer to conspiratorial muttering than to forest calm.
What it really means
Psithurism is routinely accused of being fake — one of those words invented on the internet to sound beautiful, with no dictionary behind it.
It's in the OED, with earliest evidence from Leigh Hunt in 1848. It's also in Collins, in Cambridge, and in Dictionary.com, which dates its first recorded English use to 1870–75. Archaic and rare, certainly. Fictitious, no — and it predates the internet by roughly a century and a half.
What is worth knowing is where the Greek came from, because it isn't tranquil. ψίθυρος — psíthuros — means whispering, yes, but it also means slanderous. The same word family in Greek covers furtive gossip, muttering behind hands, the sound of people talking about you. The peaceful woodland feeling English attaches to psithurism is an overlay; the root's other career was in accusations.
Which makes it a slightly better word than the listicles realise. Wind through trees does sound like whispering, and whispering is not automatically benign — there's a reason a forest at night reads as watchful rather than restful.
One practical note. If you want to be understood, the word is susurration: current, general-purpose, and applicable to any soft murmur. Psithurism is specifically arboreal, essentially obsolete, and will need explaining. Which is fine, as long as explaining it is the point.
Where it comes from
Greek — a whispering
Greek — whispering; slanderous
The Greek root carries a second sense — slanderous, gossiping — so the original word family is about malicious muttering as much as pleasant rustling. The cosy nature-word feeling is entirely an English overlay.
- 1848

- 1870–75
Dictionary.com's first-recorded date for the word in English.
In real life
- Lying in the hammock, she listened to the psithurism of the poplars overhead.
- Walking through the pinewood on a windy night, the psithurism all around them sounded uncomfortably like voices whispering.
- 'Is there a word for the sound wind makes in trees?' 'There is — psithurism. You'll just have to explain it.'
Questions
Q01Is psithurism in the dictionary?
Yes — the OED, Collins, Cambridge and Dictionary.com all carry it. Cambridge marks it 'literary' and Wiktionary 'obsolete' — a real recorded word, not a fictitious one — and the OED's earliest evidence is from Leigh Hunt in 1848.
Q02How do you say it?
The 'p' is silent: roughly SITH-yuh-riz-um. A US variant spelling, psithyrism, is also recorded.
Q03Does it really mean something peaceful?
In English usage, yes. But the Greek root psíthuros also means slanderous or gossiping, so the original word family was as much about furtive muttering as about wind in leaves. The tranquillity is something English added.
