The English privative prefixes near-, pseudo- and quasi-: Approximation and 'disproximation'

The English prefixes near-, pseudo- and quasi- are privative, in that whatever essential property their morphological base expresses is not strictly possessed by an entity characterized as near-/pseudo-/quasi-X. However, we claim this meaning precise enough hypothesize near- approximative meaning, whereas ‘disproximative’, expressing the idea of ‘falling short’ a standard. Distributional-semantic findings partially support this, shares more bases with than it does pseudo-. Near- most productive, presenting default choice, while least productive. We also observe specific tendency to select negative semantic prosody (near-deadly, near-fatal), combine, without any evaluative legal-administrative (quasi-diplomatic, quasi-governmental), terms from scientific domain. Further qualitative observations about these made.
