The man described had a visual agnosia rather than a language deficit. He literally did not See a glove, he saw what we would see - "a unicursal plane infolded on itself with five outpouchings." You or I would then interpret that visual information as a thing that you put on your hand which is called a glove. He could not interpret the visual information usefully. Most likely if you asked him what he would put on his hands if they were cold he would say "gloves."
There are a few people who although blind since birth had a surgical repair in adulthood which gave them the use of their eyes . The majority did not learn to functionally "see." One stated that although he could instantly recognize a triangle by putting his hand on it he would have to deliberately count the sides and corners to visually figure out what it was. "I see people but they look like trees walking around."
