`titrebEmilia Hilgert, An indicator of massiveness: the enigmatic un peu de`/titreb This article highlights the key dimensions that structure the opposition massif/comptable through the contrast between peu de, compatible with both types of nouns, and un peu de, which combines only with mass nouns. Examination of the opposition between these two expressions, considered only as determiners, is successively done according to the number being expressed or not, depending on the semantic variability or invariability relative to a standard, and according to the kleiberian concept of occurrences which reorders the criteria of intrinsic or contingent limits and of internal homogeneity/heterogeneity specific to massive or countable occurrences.
