Our reading
An editorial interpretation.
The line is a playful, invented-word compliment: generous or high-minded character makes even the least imposing person seem larger. Nobility of spirit is credited with lifting people up, so that someone small in standing or stature grows in dignity. The made-up verb gives the sentiment a mock-solemn ring.
