\"Gable\" has always given me trouble, as it can mean different things depending on one's background. For example, I always understood GABLE to mean the space between the pitched parts of a roof. And NOW I know that it means other things as well - pretty cool!
To me, a parallel to gable is bulkhead, and just as interesting a word. I have known bulkhead from airplanes - I prefer to sit behind the bulkhead, on the aisle. But in looking up the word on the Internet I came up with the following, from The Free Dictionary:
bulk·head (blkhd)n.
1.
a. One of the upright partitions dividing a ship into compartments and serving to add structural rigidity and to prevent the spread of leakage or fire.
b. A partition or wall serving a similar purpose in a vehicle, such as an aircraft or spacecraft.
2. A wall or an embankment, as in a mine or along a waterfront, that acts as a protective barrier.
3.
Chiefly New England A horizontal or sloping structure providing access to a cellar stairway.
And from the Thesaurus, also at The Free Dictionary:
Noun 1. bulkhead - a partition that divides a ship or plane into compartments
partition, divider - a vertical structure that divides or separates (as a wall divides one room from another)
ship - a vessel that carries passengers or freight
So - I actually learned what a ship is!!! NOT as cool as eCabs, but still fun
