Not important, significant, or having little or no effect; something so minor that it doesn't really matter.
Prefix 'in-' (not) plus 'consequential' from Latin 'consequentia' (result, consequence). Built to describe things that don't have significant consequences or results.
Despite sounding like a powerful word, 'inconsequential' actually means the opposite—it's a perfect example of how English uses long, impressive-sounding words to describe things that basically don't matter at all.
