Outstanding concert in marquee, but only one tango (9)
I believe the answer is:
prominent
'outstanding' is the definition.
(I know that outstanding can be written as prominent)
'concert in marquee but only one tango' is the wordplay.
I cannot quite understand how this works, but
'concert' could be 'prom' (abbreviation for promenade concert) and 'prom' is found within the answer.
'in' is within the answer.
'tango' could be 't' (phonetic alphabet: alpha, bravo, charlie etc.) and 't' is found within the answer.
The remaining letters 'en' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for prominent that I've seen before include "Well-known" , "Conspicuous or outstanding" , "Conspicuous in position or importance" , "Important; protuberant" , "Noticeable or notable" .)
