Hi thanks for correcting but I already mentioned I have used it "volontary wrongly" and as you must know "pleonasm" is related to "redundancy", term we often see with SMLOL, me too! But that's when I noticed he misused the word.
"I am just trying to remove the confusion of using the term "SM" as a pleonasm for "two tanks set-up" ".
Using an abbreviation in place of a longer phrase is actually the opposite of a pleonasm.
ple·o·nasm
/ˈplēəˌnazəm/
noun
- the use of more words than are necessary to convey meaning (e.g. see with one's eyes ), either as a fault of style or for emphasis.
But lets stop being too pedantic and back to the topic
