Morphology

significantly = significant (semi-transparent) = significant + ly

Formally derived from 'significant' + '-ly', but the statistical meaning ('unlikely to be due to chance') is a specialized extension that may not be obvious from the general sense 'important'.

Etymology

In science and statistics the word significantly has the same root, from Latin significare and sign meaning 'to show' or 'mark', like a 'sign' that points to something real. So a result that is significantly different is one that 'shows' a real change and is not likely to be only by chance.
