If you have experience with Lean Manufacturing you’ll be aware that Flow is one of the fundamental concepts.
Linguistics nerd that I am it turns out the transation of Flow in Greek and Latin.
From the Thracian Glossary
ars- ‘to flow; current, river’ [Old-Pruss. RN Arsio, Arse, Old-Ind. árs,ati ‘to flow’, Hitt. arš- ‘the same’].
From Basic Latin Elements List:
fluct-Â (Latin: flow, wave)
 Flow no longer has the same ring as it used to.
