  This paper proposes a formalization of the class of sentences quantified by
\textit{most}, which is also interpreted as {\em proportion of} or {\em
majority of} depending on the domain of discourse. We consider sentences of the
form "\textit{Most A are B}", where \textit{A} and \textit{B} are plural nouns
and the interpretations of $ A $ and $ B $ are infinite subsets of $ \mathbb{N}
$. There are two widely used semantics for \textit{Most A are B}: (i) $C(A \cap
B) > C(A\setminus B) $ and (ii) $ C(A\cap B) > \dfrac{C(A)}{2} $, where $ C(X)
$ denotes the cardinality of a given finite set $ X $. Although (i) is more
descriptive than (ii), it also produces a considerable amount of insensitivity
for certain sets. Since the quantifier {\em most} has a solid cardinal
behaviour under the interpretation {\em majority} and has a slightly more
statistical behaviour under the interpretation {\em proportional of}, we
consider an alternative approach in deciding quantity-related statements
regarding infinite sets. For this we introduce a new semantics using {\em
natural density} for sentences in which interpretations of their nouns are
infinite subsets of $ \mathbb{N} $, along with a list of the axiomatization of
the concept of natural density. In other words, we take the standard definition
of the semantics of \textit{most} but define it as applying to finite
approximations of infinite sets computed to the limit.
