the.com/disfluency
The 'um' holding your sentence together while your brain catches up.
means A break or hesitation in speech — like a stutter, repetition, or filler word — that interrupts the smooth flow of talking.
from Built from 'fluency,' which traces to Latin fluere, 'to flow' (the same root that gives us 'fluid' and 'fluent'). Slap the negating prefix 'dis-' on front and you get the opposite of flow: speech that stalls, stutters, or eddies instead of running smoothly. The term itself is a modern coinage from linguistics and speech pathology, built to name scientifically what everyone already recognized by ear — the 'um,' the false start, the repeated syllable.
