i just noticed today that some words has already expanded its use to different modes. like for example the word "flash". before, we only know it as a light that glows intermittently.
now, when you say "flash" it can refer to
1. flash in the camera
2. flash the superhero
3. flash gordon
4. flash software
5. flash drive/memory
6. flash video or known as flv
and you might even think of other things. words like these can confuse some of our elders as they might only know the flash in the camera.
