Dragons Den here I come!!

Bus down to Edinburgh today to do some bunny sitting.
To pass the time on the bus, I look at car number plates and try to make words from them
e.g.
NSY - Noisy
HYD - Hybrid
UUY - unusually
My rules are the word must start with the first letter and the letters must be in the right order
I can't help feeling these ones should be easy
HHB
LFH
ACP
No dictionaries allowed!!!
P.S. Why are they called number plates when most of them are made up of letters!!!
