Each image in the Primary and Secondary columns clues a single word, and the words in each column are sorted alphabetically. Each resulting word in the Primary column can be paired with a word in the Secondary column to form a common two-word phrase.
As the flavor text suggests, this puzzle is about Latin abbreviations. Each two-word phrase from the images can be abbreviated in the same way as a common Latin two-word phrase. The Latin two-word phrases can be entered into the boxes at the bottom, based on the number of letters in each word. Letters can be picked out of each Latin word based on the numerical indexes next to the corresponding image (e.g. MINERAL becomes MODUS and has a 5 next to it, so take the 5th letter of MODUS).
Reading the highlighted letters in order spells SERIES OF THREE, which clues the final answer, TRILOGY.
