What does the word rhythm have to do with flowing? Let’s find out in this Adventure in Etymology.

Meanings of rhythm [ˈɹɪð.m̩] include:

• The variation of strong and weak elements (such as duration, accent) of sounds, notably in speech or music, over time; a beat or meter.
• A specifically defined pattern of such variation.
• A flow, repetition or regularity

It comes from Latin rhythmus [ˈrʰytʰ.mʊs] (rhythm), from Ancient Greek ῥῠθμός [r̥ytʰ.mós] (vibration, rhythm, measure, order, form), from Proto-Hellenic *hrutʰmós, from PIE *sru-dʰ-mo-s from *srew- (to flow, stream) [source].

Words from the same roots include catarrh, stream, rheumatism and rhyme / rime in English, ρέω (réo – to flow, run) in Greek, ritmo (rhythm, pace) in Spanish, strøm ([electrical] current, flow, stream) in Danish, srūti (to flow, stream, run) in Lithuanian, and sruth (stream, current, flow) in Irish [source].

The word logorrhea (excessive talkativeness, the excessive use of words in writing; excessive and often uncontrollable speaking due to a mental disorder) also comes from the same roots. It’s made up of logo- (word speech) and -rrhea (flowing), and was possibly modelled on verbal diarrhea – diarrhea also comes from the same roots [source].

Part of the word maelstrom (a large and violent whirlpool, a chaotic or turbulent situation) is also related. It comes from Dutch maelstrom (whirlpool), ultimately from PIE *melh₂- (to crush, grind) and *srew- (to flow, stream) [source].
