Range/scope: Tradition: Tmesis, logically indivisible operator: either or: E.g. either both: young and stupid or evil - or either young or stupid and evil
Range: problem with descriptions, not with names - E.g. it is (logically) chronologically possible that Caesar was the father of Brutus - description: Caesar = man who not begat Brutus - then: narrow scope: logical impossibility; the whole sentence is wrong - long scope: someone who is described among other things as non-producer of Brutus ... the sentence remains true.
