Heed secretary initially desiring thing for scribbling (7)
I believe the answer is:
notepad
'thing for scribbling' is the definition.
I can't tell whether this defines the answer.
'heed secretary initially desiring' is the wordplay.
'heed' becomes 'note' (I've seen this in another clue).
'secretary' becomes 'PA' (abbreviation for personal assistant).
'initially' says to take the initial letters.
The initial letter of 'desiring' is 'd'.
'note'+'pa'+'d'='NOTEPAD'
Can you help me to learn more?
(Other definitions for notepad that I've seen before include "Tablet" , "Place for recording" , "On which one writes" , "Item to write on" , "aide-memoire" .)
