Psithurism is the rustling or whispering sound of wind moving through trees.
Not coined by an identifiable individual — an English borrowing from Greek, not a neologism.
// Where it sits
Rare and archaic, but real. It gets accused of being fake far more than it deserves.
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
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.
Myths & misconceptions
Psithurism is a made-up internet word with no dictionary standing.
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.
It means the peaceful sound of leaves.
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.
Compare & contrast
Psithurism vs susurration
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.

Questions people ask
- Is 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.
- How do you say it?
- The 'p' is silent: roughly SITH-yuh-riz-um. A US variant spelling, psithyrism, is also recorded.
- Does 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.
