Root Breakdown

=unison

uni- (one) + son (sound) = 'one sound.' When many voices sing the exact same note, they merge into a single sound. From the choir loft the word spread to any coordinated action — moving 'in unison' means moving as one.

Why It Means This

Almost always used in the fixed phrase 'in unison.' The literal music sense (many voices, one note) came first; the figurative sense (people acting as one) grew straight out of it. Note the spelling keeps 'son' (sound), not 'sound' — uni- + sonus.

Common Collocations

  • 1.in unison齐声地,一致地
