Except for its subtype Approximator, there are no prototypical adpositions for this category in English: wherever quantity–quantified relations are marked by a preposition, the preposition is on the quantified thing, and is thus labeled QuantityItem.

QuantityValue can, however, appear as the scene role with very specific predicates like in #001:

• The deaths numbered in the thousands. (QuantityValue↝Locus) 001

• There were thousands of deaths. (QuantityItem) 002
