Some opportune moment to hold up consumer choices (4)
I believe the answer is:
menu
'some opportune moment to hold up consumer choices' is the definition.
I can't tell whether this definition defines the answer.
'some opportune moment to hold up' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'to hold up' shows that the letters should be reversed in order (I've seen 'held up' mean this).
'unem' is hidden in the letters of 'opportune moment'.
'unem' in reverse letter order is 'MENU'.
Can you help me to learn more?
(Other definitions for menu that I've seen before include "Range of dishes available" , "List of dishes available in restaurant" , "that can appear on computer screen" , "List of options" , "List of food items on offer" .)
