Not having a thick or sticky consistency; flowing easily.
Water is nonviscous, allowing it to flow freely.
Nonviscous → It is formed from "non-" (meaning not) and "viscous" (from Latin "viscosus", meaning sticky or thick). The word "nonviscous" means not sticky or thick.
Think of 'not' ('non-') being combined with 'sticky' ('viscous') to remember that 'nonviscous' describes something that is not sticky.
