On: Viking Ship Museum in Denmark announces the discovery of the largest cog

[card_zero]

They have the same etymological root, from a Proto-Germanic word for a lump, which is the tooth (cog) on a cogwheel, or the round bulky lump of a cog ship.

[twic → card_zero]

So they're cognates.

[pimlottc → twic]

Cog mates, even

[WJW → twic]

Nice

[card_zero → twic]

Godammit

[imoverclocked → card_zero]

No... Cog, damnit.

[jonahx → twic]

But "cognate" is not.
