Re: Partially-heard words. (or phrases?)

It looks like what people are saying is something like this;
In almost all natlangs, there is no way to _always_ be _certain_; but in many
(most?) natlangs, there are a few ways to _often_ be certain, and
_always_ "have a clue".
And the same applies to segregating words; and to segregating morphemes;
and to syllabifying.
Is that true?
