Mhm.

But that still leaves one wondering about the expression.

See, the phrase "Dead as a doornail"
arises from synonymity--
Doornails must be dead on, or the door hangs wrong.
Somehow, it moved from meaning
"As well-placed as a doornail"
to mean "Lifeless as a doornail"
which doesn't make a lot of sense...

but "perpendicular as rain"
or "crafted as rain"
doesn't make particular sense to begin with...

if the phrase came to us from Latin,
"non-sinister as rain" might make sense...

btw, radargrrl thought I should flist you,
and who am I to argue?
