In polysemy and hypernymy categories, some key differences were noted that were not apparent in the earlier study.
Philips introduces the concept of "ideological polysemy" to capture the way multiple levels of ideology may be implicated in a single utterance.
This kind of polysemy is discussed in section 6.
The answer, it seems, would have to explicitly recognize that this particular kind of polysemy is different from other kinds.
The answers to questions (c) and (d) are also closely related and depend on some kind of understanding of the important issue of polysemy.
Since over-verbs are stored in memory as distinct from the preposition over, it is no wonder that the prefix over- develops its own polysemy structure.
Handling graded phenomena, fine-grained issues of polysemy, change and context-dependency, especially at the levels of semantics and pragmatics, are examples of problematic issues.
Cognitive linguists in particular have been interested in the polysemy of prepositions and the relations between their various senses.
