Silent H (Update: link removed because it no longer works), a description of its use and role in history:
A silent h can be put anywhere you want, precisely because it is silent. So for example, it is equally proper to spell it Gandih, Gahndi, hGandi and even Gandhhhhhhhi.
The silent h is very flexible. When I’m talking, I’ll toss in a silent h every third syllable, and no one seems to mind. I’m not trying to show off by doing it. I just like the way it doesn’t sound.
Little known fact: The original name for the stealth bomber was Hhhhhhh, where every h but the fourth one is silent.
