Parts and subclasses[edit]
After careful review of relevant edit histories, I'm removing preposition (Q4833830) and postposition (Q161873) as parts of adposition (Q134316), and making the corresponding changes to those items.
Reason: An adposition can be either a preposition ("within an hour"), a postposition ("an hour ago"), or a circumposition, but not two (or three) of them at the same time, which is why those three items are subclasses. A part typically isn't identical to the item it is a part of, and may also coexist with other parts. An adposition never contains both a preposition and a postposition at the same time however ("within an hour ago"?); they are mutually exclusive, much like a bicycle or a boat aren't parts of a vehicle, but subclasses of it.
In case there is still some disagreement over this, let's discuss it here. In general, I consider simultaneous claims that A is a subclass of (P279) B and also a part of (P361) B to be mistakes, perhaps added by different editors who may have different definitions of the items in mind (there may of course be exceptions to this rule of thumb). --SM5POR (talk) 14:54, 8 January 2022 (UTC)
