Augmentation of honour
In heraldry, an augmentation (often termed augmentation of honour or sometimes augmentation of arms) is a modification or addition to a coat of arms, typically given by a monarch as either a mere mark of favour, or a reward or recognition for some meritorious act. The grants of entire new coats by monarchs as a reward are not augmentations, but rather grants of arms, and (in theory) an augmentation mistakenly given to someone who did not have a right to a coat would be nugatory.

Emperor Charles V, who was also King of Spain, granted to Juan Sebastián Elcano, the surviving commander of the Ferdinand Magellan expedition that first circumnavigated the world, an augmentation of arms consisting a world globe with the words Primus circumdedisti me (Latin: "You first encircled me").
