LOL, now we're down to semantics for sure !
But actually, NASA does call them "motors". I'm not not referring to the main engine which ran on liquid fuel. I'm talking about the solid fuel boosters on the sides.

I don't see them as either, just a glorified roman candles.
It's not semantics. it's accuracy. Like not calling a whale a fish.
I reckon I'm chuckling at that reply ! Those two sentences don't seem to fit together well. On the one hand you are saying we should be accurate in our descriptions.
In the other sentence you are comparing high tech rocket motors to cheap backyard fireworks.
They are both just tubes of propellant that are ignited and can’t be shut off or controlled until they run out of fuel. The only difference is they have some control of the nozzle direction on a SRB. Doesn’’t sound very high tec to me.
Using that definition a firearm could be an engine. Or would it be a motor?
