The doldrums are a flat, stuck, going-nowhere state — of a mood, a ship, or a belt of ocean near the equator.
Not coined — a colloquial English formation.
// Where it sits
The word arrived as a mood and acquired an ocean afterwards.
What it really means
Everyone knows this one: the doldrums are the belt of dead calm near the equator where sailing ships could sit for weeks with no wind, and the phrase for feeling flat and stuck is a metaphor borrowed from those becalmed sailors.
It runs the other way. The dates are unambiguous. 1803 — low spirits, the blues, the dumps. 1824 — the nautical sense of being becalmed. 1848 — the equatorial region itself.
So the mood came first by forty-five years, and the ocean was named after the feeling. The likeliest mechanism is a simple misreading: sailors said they were in the doldrums, meaning fed up and going nowhere, and the phrase looked enough like a place name that eventually it became one.
The word's construction is equally makeshift. There was an obsolete doldrum, a dull or sluggish person, from dull — and the -rums ending isn't a suffix at all. It was copied off tantrum, purely because it sounded right. English built a word by taking an adjective and stapling the back half of an unrelated noun onto it.
One small correction on the geography, since the word did eventually earn it. The region isn't a line. It's the Intertropical Convergence Zone — a shifting belt of calms, squalls and light baffling winds that migrates with the seasons, and is considerably less peaceful than the phrase suggests.
Where it comes from
The -rums isn't a real suffix. The first element is probably 'dulled', with the ending perhaps patterned on tantrum.
Myths & misconceptions
The mood sense is a metaphor taken from sailors stuck at the equator.
Exactly backwards. The mood sense is dated to 1803, the nautical sense to 1824, and the geographical region only to 1848. The ocean was named after the mood — apparently because 'in the doldrums' got misread as naming a place.
The doldrums are a fixed band on the map.
The belt referred to — now the Intertropical Convergence Zone — is a shifting region of calms, squalls and light baffling winds, not a fixed line. It migrates seasonally.
Compare & contrast
Doldrums vs ennui
Ennui is boredom with a philosophy attached — a French word carrying a whole literature about meaninglessness. Doldrums is boredom with no wind: flatter, less articulate, and considerably more nautical by accident.

Questions people ask
- Which came first, the mood or the ocean?
- The mood, by decades. 'Low spirits' is dated to 1803; the nautical sense of being becalmed to 1824; the equatorial region only to 1848. The geography was named after the feeling, not the reverse.
- Why is it always plural?
- Because it was formed on the model of 'tantrum' — the -rums ending is analogical rather than a real suffix — and it survives mainly inside the fixed phrase 'in the doldrums'.
- What's the region called scientifically?
- The Intertropical Convergence Zone. It's a shifting belt of calms, squalls and light baffling winds rather than a fixed line on the map.
