Parsimonious

"Parsimonious" has too many syllables. For a word that means extreme frugality, it takes up too much space. "Frugal" has money connotations.

"Austere" is a strict word. Stark, bleak, bare - words that haunt.

A "simple", was a medicine made from one ingredient only. The meaning is now more complicated.

Simply: I strive to convey what is essential. Parsimoniously.
