These are different for the way light shines from objects described by these adjectives. 1. A light that is changing or flashing quickly, but does not hurt the eyes (is not very bright). 2. A constant light, not very bright, usually means the light is reflected off of the object. 3. A weak, short-lived light, usually caused by reflection off the object. 4. A somewhat strong, changing light. This usually has a positive connotation. 5. A bunch of small, flashing lights. Examples 1. The north star began to glimmer, blinking in and out of vision. 2. The sunlight gleamed off of the surface of the well-polished car. 3. Walking by the cat on the sidewalk, a glint in its eye caught my attention. 4. The dolphin jumped out of the water, its body glistening beautifully as sunlight passed over it. 5. The sequins on the girl's dress glittered as she walked through the room. The differences aren't big, but I hope this clarifies a bit!
