Detail #55: Wackernagel adposition blocking

If an adjective is extracted from a PP with a Wackernagel-position adposition in it, the adposition becomes a preposition instead. Adjective extraction has the following uses, functions and general grammatical properties:

• Polar questions involving an adpositional phrase with an adjective - 

in the red car: the in red.obl car.obl, or red.obl in car.obl  

is it in the red car?: red.obl.Q it is in the car.obl, red.obl.Q it is in car.obl

If there is a PP without an adjective in it, the preposition may be stranded and the noun fronted. 

•  Emphasizing the adjective. Red.obl it is in house.obl - It is in the red house. 
• Presence of (intransitive/particle-like) adpositions nearby
