Though this idiom is by no means very common, one comes across it now and then. (I just came across it again today, which is why I'm asking this question.)

Why is a "brown study" so named?

Do you have a link or some more context? I've never heard this expression before. –  Kit Z. Fox Jul 14 '11 at 14:35
I just came across the term used in a June 1859 letter by George A. Custer: "...I will expect a 'real long' letter in answer to this, which will contain all the news of the young folks, enough to keep me in a ‘brown study’ a week" (George A. Custer to Minnie St. John, 25 June 1959) –  user85399 Jul 17 '14 at 18:50

From TheFreeDictionary.com:

brown study n a mood of deep absorption or thoughtfulness; reverie ...
Gloomy meditation or melancholy is known as being in a brown study.

This is a somewhat archaic usage (it may be a rural or Southern U.S. regionalism, but I don't have access to my tools for tracking that down just at the moment), although it has been used in poetry to good effect. Consider this stanza from John Crowe Ransom's "Bells for John Whiteside's Daughter":

There was such speed in her little body,
And such lightness in her footfall,
It is no wonder her brown study astonishes us all

He's talking about death as a "brown study" in an example of understatement.


@Kit brings up a good point. "Brown" used to mean gloomy exclusively. From Etymonline:

brown O.E. brun "dark, dusky," only developing a definite color sense 13c

Re "may be a rural or Southern U.S. regionalism": I seem to recall reading it in Conan Doyle. –  msh210 Jul 14 '11 at 15:21
This doesn't appear to actually answer the question? Or am I missing something? –  MrHen Jul 14 '11 at 19:28
'brown study' occurs (at least) twice in the novel 'Victory' by Joseph Conrad, who is British, which suggests that it's not an American expression. –  Jona Christopher Sahnwaldt Jul 17 '14 at 21:07
According to Google's Ngram Viewer though, the expression is slightly more common in American English: books.google.com/ngrams/graph?content=brown+study –  Jona Christopher Sahnwaldt Jul 17 '14 at 21:16

Slightly surprisingly, since neither of its words now seems to fit the meaning, brown study was originally a tautology and pleonasm.

The OED first cites it from 1552*. As other answers note, brown at this date could mean dusky, dark more generally than today, and hence figuratively gloomy, serious. But besides that, study also had a slew of now-obsolete meanings, including a state of mental perplexity or anxious thought and a state of reverie or abstraction, with uses like:

He was in suche a study he herd not what Gouernayle said.
      —Malory, Morte d'Arthur, 1470–85

I was at first in a study what to do, at last I promised.
      —R. Meeke, Diary, 1689

So a brown study then was closely analogous to the not-yet-so-opaque a blue funk. To be in a study was bad already; a brown study really served to emphasise the gloom.

* in the rather extraordinary-sounding Manifest Detection Diceplay, which turns out upon googling to be a pamphlet on cheating at cards, A Manifest Detection of the Most Vyle and Detestable Form of Diceplay, by one Gilbert White.

According to the Phrase Finder, brown study is very old usage of "brown" to indicate a gloomy mood and "study" in the sense of deep thought. More modernly, we would probably more immediately grasp "black mood," since black is the new brown, as it were.

The closest meaning today of 'brown study' is 'brooding'. As used into the mid-20th century, didn't just mean a melancholy mood or 'reverie' and it didn't mean 'depressed' in our usual sense. It meant thinking so deeply about something troubling that one becomes wrapped up in it and temporarily cut off from other people or asocial. In essence, if one is in a brown study, one is 'studying' (thinking hard about) something in a 'brown' or darkly shadowed mood.The assumption was, though, that people going into brown studies occasionally and then come out of them.

There's nothing American about this phrase. It was widely used in British English, too. Seems to have one out of fashion with the passing of time (and it's not taught in schools today, which probably explains the decline).

yes i've seen it in the UK. it is not a common expression, and generally used in writing rather than speech. however the idiomatic use of "study" mentioned by @PLL was perhaps not quite obsolete in my West Yorkshire childhood in the 1950's - "when she realized...her face was a study" - though in the simplistic thought of a child i merely interpreted the word as meaning "worthy of study" –  David Holden Aug 7 '14 at 12:16
