Detail #439: Quasi-parts of speech and quasi-constituents and the Locus of the Abessive

Different languages are analyzed with different sets of parts of speech and constituents/parts of sentences. To some extent these boil down to grammatical traditions, but to a great extent they also boil down to actual grammatical phenomena. However, if we were to compare, say, Swedish and English, the differences are largely superficial: both descriptive traditions work with barely any modifications to describe either language. A trivial example: Swedish grammar tradition has "subjunctions", which in the English tradition are subsumed under "conjunctions". Subjunctions are words that introduce subclauses, i.e. subordinating conjunctions. A description of English would be marginally different if this concept was introduced.

In some languages, however, distinguishing adjectives from nouns - or adjectives from verbs in some other languages - makes way less sense. Applying such a distinction would be looking at it through a decidedly foreign lens. Sometimes, which part of speech a word belongs to is hard to pinpoint: a word may be both a verb and an adverb, or a noun and an adverb, or a noun and an adjective, etc.

A thing that interests me, however, are a variety of ways in which constituents and parts of speech may behave in ways that justify considering them some kind of quasi-PoS or quasi-constituent, constituents that show some kind of uniformity, but cut across other constituents.

One such example I have been sketching over recent months is what I chose to call "the locus of the abessive". This locus is marked by a certain case (which however also is used for some other constituents), but can appear as subjects, objects, indirect objects, possessors, possessums and other constituents. The abessive itself could also be considered a type of quasi-constituent.

The syntax of this entity gets complicated. First of all, the locus can be any of the following:

• topic
  
• subject: I miss her
  
• object: he deprived them of shelter
  
• indirect object: they gave him no food
• location: there is no joy in Aylesbury
• possessor: the orphan's mom
• possessum: the man's widow
• infinitives of various functions: there's no reason to hate him

What if the locus of the abessive could be coordinated over gaps, even when it isn't the same role? 'They deprived him of shelter and gave no food' would then have 'him' as the indirect object of 'gave'. This could get really tricky once possessors and possessums and infinitives start getting involved.
