Double language, originally a feminist concept, proposes that women, lacking equal voice in a patriarchal society, must express their differences subtly, without directly opposing the dominant voice privileged to the father, husband, son, or male partner.

A standard humorous example involves a gathering of couples in which one husband starts telling his wife how he expects things to be, to which his wife answers, "Yes, dear."

"Yes" in this situation may have more than one meaning for more than one audience.

The husband hears "yes" and feels validated.

However, other women may hear her voice intoning reservations, or that the wife says yes to calm the husband. "Yes" may not really agree with what he's saying but instead indicates only that she's listening.

Such uses of double language may be observed also in ethnic minorities. A familiar example is blues music, iwhose lyrics and melody offer alternating moods of joy and sadness.

The following passage from chapter 2 of Frederick Douglass's slave narrative, Narrative of the Life of Frederick Douglass, demonstrates how double language is not always a conscious strategy but one rising from conditions:

 . . . The home plantation of Colonel Lloyd wore the appearance of a country village. All the mechanical operations for all the farms were performed here. The shoemaking and mending, the blacksmithing, cartwrighting, coopering, weaving, and grain-grinding, were all performed by the slaves on the home plantation. The whole place wore a business-like aspect very unlike the neighboring farms. The number of houses, too, conspired to give it advantage over the neighboring farms. It was called by the slaves the Great House Farm. Few privileges were esteemed higher, by the slaves of the out-farms, than that of being selected to do errands at the Great House Farm. It was associated in their minds with greatness. . . .

The slaves selected to go to the Great House Farm, for the monthly allowance for themselves and their fellow-slaves, were peculiarly enthusiastic. While on their way, they would make the dense old woods, for miles around, reverberate with their wild songs, revealing at once the highest joy and the deepest sadness. They would compose and sing as they went along, consulting neither time nor tune. The thought that came up, came out—if not in the word, in the sound;—and as frequently in the one as in the other. They would sometimes sing the most pathetic sentiment in the most rapturous tone, and the most rapturous sentiment in the most pathetic tone. Into all of their songs they would manage to weave something of the Great House Farm. Especially would they do this, when leaving home. They would then sing most exultingly the following words:—

"I am going away to the Great House Farm!

O, yea! O, yea! O!" This they would sing, as a chorus, to words which to many would seem unmeaning jargon, but which, nevertheless, were full of meaning to themselves. I have sometimes thought that the mere hearing of those songs would do more to impress some minds with the horrible character of slavery, than the reading of whole volumes of philosophy on the subject could do.

I did not, when a slave, understand the deep meaning of those rude and apparently incoherent songs. I was myself within the circle; so that I neither saw nor heard as those without might see and hear. They told a tale of woe which was then altogether beyond my feeble comprehension; they were tones loud, long, and deep; they breathed the prayer and complaint of souls boiling over with the bitterest anguish. Every tone was a testimony against slavery, and a prayer to God for deliverance from chains. The hearing of those wild notes always depressed my spirit, and filled me with ineffable sadness. I have frequently found myself in tears while hearing them. The mere recurrence to those songs, even now, afflicts me; and while I am writing these lines, an expression of feeling has already found its way down my cheek. To those songs I trace my first glimmering conception of the dehumanizing character of slavery. . . .

I have often been utterly astonished, since I came to the north, to find persons who could speak of the singing, among slaves, as evidence of their contentment and happiness. It is impossible to conceive of a greater mistake. Slaves sing most when they are most unhappy. . . .
