  Over the decades, the application of mechanical force to influence chemical
reactions has been called by various names: mechanochemistry, tribochemistry,
mechanical alloying, to name but a few. The evolution of these terms has
largely mirrored the understanding of the field. But what is meant by these
terms, why have they evolved, and does it really matter how a process is
called? Which parameters should be defined to describe unambiguously the
experimental conditions such that others can reproduce the results, or to allow
a meaningful comparison between processes explored under different conditions?
Can the information on the process be encoded in a clear, concise, and
self-explanatory way? We address these questions in this Opinion contribution,
which we hop
