Do you mean "statement" or really mean "expression" - understanding that >>> the term "expression" (of a language) includes things like "ngs lik"
from this statement.
It turns out that I must have remembered this from:
*Russell’s Logical Atomism*
the claim that the world consists of a plurality of
independently existing things exhibiting qualities
and standing in relations. According to logical
atomism, all truths are ultimately dependent upon
a layer of atomic facts, which consist either of a
simple particular exhibiting a quality, or multiple
simple particulars standing in a relation.

I bought his book a few decades ago.
According to that link, Russel's 'expression' is more restrictive that Haskell Curry's, Curry considered "ngs lik" to be an expression while
Russel is there said to consider "the King of France" to be an
expression, I suppose giving the two noun phrases as the only two
examples, as they do, is intended to exclude the supposition that "ngs
lik" is an expression, which Curry allows. I wonder whether Curry misunderstood or adopted/formed a second school.
