Morphology
of + the + first + water
The meaning 'of the highest quality' is idiomatic and historically based (e.g. old usage referring to gem quality), so a learner who knows 'first' and 'water' would not reliably derive this sense — 'water' does not transparently signal quality. This phrase is relatively archaic and language-specific, making its meaning unpredictable without prior exposure.
Etymology
Of the first water may come from how people judged pearls and gems long ago: they called the very best bright, clear pearls 'first water'. So, saying something is of the first water means it is 'of the highest quality'.
