#TIL a new set of #word­s: allide and allision.
Like collide and collision, but no »co«. To crash into something immobile.
And, yes, that is about the bridge thing.

#allide #allision
#vocabulary #English

Wenn man Zusammenstoß für Kollision/collision sagt, kann man Anstoß für allision nehmen, oder gegen <foo> stoßen.
The word could be transitive, »the ship allided the bridge« but as far as i can tell it is used intransitively, »the ship allided *with* the bridge«.
Oh, i found an »#allision« in the wild, albeit pronounced more like a·lesion

@ospalh Interesting. Doesn't seem to be in popular use. Merriam-Webster lists "allision", but not "allide".
I'm not sure a separate word is needed, since both objects are still involved in the *llision, both get damaged, etc. To my mind, "collision" never had the connotation that both objects had to be moving. I can talk about an aircraft colliding with a mountain without any qualms.

@hopfgeist
It seems to be a legal term.
From Wikipedia
»… the presumption that the moving vessel is at fault, stating that "presumption derives from the common-sense observation that moving vessels do not usually collide with stationary objects unless the [moving] vessel is mishandled in some way"«

Admiralty law - Wikipedia

If some warning lights are out on a bridge, or a ship at anchor, the operator might be at fault to some degree, tho. (Talking insurance here.)

But in this case, there seemed to be lots of lights on the Key Bridge, and possibly enuf ambient light to see it even without them.
The whole thing seems odd, so odd that lots of organizations and people felt the need to point it out that it seems to be accident, no deliberate act.

So, looks like a power failure on the ship.
That *is* a nasty situation.
And in one foto yu can see the port anchor chain, as if they had dropped anchor.
Maybe they did all they could in that situation.
