Explanations

Each of the four groups was a closed set of four and one of the group was missing from each of the four clues. The missing words are shown in the clues below highlighted in blue. The groups were:
GROUP A: card suits (SPADES, HEARTS, DIAMONDS, CLUBS)
GROUP B: elements (AIR, EARTH, FIRE, WATER)
GROUP C: directions (NORTH, EAST, SOUTH, WEST)
GROUP D: seasons (SPRING, SUMMER, AUTUMN, WINTER)

The solutions for these then needed to be ordered alphabetically, and the fourth letter of the fourth words extracted:
GROUP A: ENDS, LATTICE, PASSED, RACQUETS => Q
GROUP B: ALFRESCO, BOMBARD, CANED, GROUND => U
GROUP C: ASKEW, BARGE IN, BARNS, GALAPAGOS => A
GROUP D: ABACUS, ARISE, CHATEAU, TUNDRA => D
This gave QUAD as the four letter word to be submitted.
