Old reliables begin to come down and come round in Florida (7)
I believe the answer is:
orlando
'in florida' is the definition.
(I've seen this before)
'old reliables begin to come down and come round' is the wordplay.
'begin to' indicates taking the first letters (I've seen 'beginning to' mean this).
'come down' becomes 'land' (to land is to come down after flying).
'and' means one lot of letters go next to another.
'come round' becomes 'o' (I can't explain this - if you can you should believe this answer much more).
The first letters of 'old reliables' is 'or'.
'or'+'land'+'o'='ORLANDO'
Can you help me to learn more?
(Other definitions for orlando that I've seen before include "Florida city; V. Woolf book" , "Rosalind's lover" , "American themepark location" , "___ Gibbons, English composer of madrigals - Florida resort city" , "Bloom for one" .)
