She often drops an H (5)

I believe the answer is:

norah

I'm a little stuck... Click here to teach me more about this clue!

'she' is the definition.

'often drops an h' is the wordplay.
'often' becomes 'nor' (I can't explain this - if you can you should believe this answer much more).
'drops' says to take the initial letters (I've seen 'drop of' mean this).
The first letter of 'an' is 'a'.
'nor'+'a'+'h'='NORAH'

Can you help me to learn more?

(Other definitions for norah that I've seen before include "Girl" , "Batty woman" , "Girl's name" .)

I've seen this clue in the Evening Standard.
