The 18 islands which make up the Faroes are connected by 23 tunnels, four of which run below the seaLook, i'm not a rocket scientist nor brain surgeon, so i'm struggling a bit here. Pls help, someone.

What's an island? Ain't it
kinda sorta like a bit of land surrounded by, not to put too fine a point on it, a body of water, which in non-lake & non-riverine contexts, some might consider a bit, well... sea-ish?

So, if one were to have, say, 18 islands, so defined, & if they were all interconnected via tunnels, then... & this seems to be the tricky bit... doesn't it
kinda sorta ipso facto mean that all said tunnels run below the seaI mean, if vehicular transport infrastructure were to connect some islands together but not be "below the sea", mightn't some vulgar cynics tend to opine these would be called, well... bridges ?

What vital concepts & facts am i missing here, pls?
🤔🤷🤯

Shetland eyes Faroes-style tunnels to replace ageing ferries

The local council says it is pushing ahead with plans to build tunnels to four outlying isles in the archipelago.

@MsDropbear42 Ah, now I get it - some of the tunnels go through rock above the water level. So if you need to get from point A to point B on a single island, you might do that using a road that takes the long way, or you might ram a tunnel through the straight line distance.

Took a while to work out, though!

@janeishly That's right, but is not what i posted about. I'm making the point that the text i quoted, is technically incorrect.
@MsDropbear42 Yes, it's terrible! But the BBC have long since abandoned any pretence at good writing, just like they can't do any kind of journalism that isn't fawning to the ultra-right wing.
