Holy place admitting use of tech's a pressing matter (8)
I believe the answer is:
priority
'holy place' is the definition.
'priority' can be an answer for 'place' (I have seen 'First place ' mean 'priority' so perhaps 'place' could also mean 'priority'). I'm not sure about the 'holy' bit.
'admitting use of tech's a pressing matter' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is found in the answer.
'matter' could be 'pr' (Pr is an example) and 'pr' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for priority that I've seen before include "the most important thing" , "Status establishing relative importance or urgency" , "Something regarded as more important than others" , "preferential treatment" , "Right to go before others" .)
