m and p are quite similar indeed, in that they are both labial.
m induces the vibration of vocal chord and makes p a vocal, to say, b.
Similarly D sound is written [face=SPIonic]nt[/face], and hard G is written [face=SPIonic]gk[/face]([face=SPIonic]g[/face] before [face=SPIonic]k[/face] is sounded ng)
If you are a Tolkien fan, see how the tengwars for Quenya mp(
) and nd(
) are used for b and d, respectively in the Beleriandic mode.
