Indeed - I neglected to account for TLR's in my comment, thus 'reflex' derives from the mirror's 'reflection' of the lens' view through the prism and viewfinder. Learned something today.
Which actually properly states my point. When not actually 'educated' sometimes Wikipedia is your friend.

Single Lens Reflex Camera"
"More recently, Sony have resurrected the pellicle mirror concept in their "single-lens translucent" (SLT) range of cameras"
