It is much larger than a letter, unless, perhaps, one carries on a correspondence with a giant from Brobdingnag.
He was going to have asked for some of the Brobdingnag raspberry-plants.
In Brobdingnag Swift is generally said to be looking, as Scott expresses it, through the other end of the telescope.
The whole man seemed but a single hand—a Brobdingnag hand affixed to the body of a Liliputian.
In the middle of the explanation a melodious sound was heard in the air above them, like a swarm of Brobdingnag bees.
A city looked at in the polishd back of a Brobdingnag spoon held lengthways, so enormously stretched-up are the houses!
Some of the incidents are devised in this sense; but we may notice that in Brobdingnag he recurs to the Lilliput view.
Give Swift his world of Lilliput and Brobdingnag respectively, and all, after that, is quite natural and probable.
In Lilliput and Brobdingnag, however, the satire scarcely goes beyond pardonable limits.
One of his own Brobdingnag raspberry-plants, swung by the angry arm of Oakly, struck off the head of his precious tulip!
(not *brobdignag), 1727, Swift's name in "Gulliver's Travels" for imaginary country where everything was on a gigantic scale.
