Land and come round about eleven (6)
I believe the answer is:
mexico
'land' is the definition.
(Mexico is an example)
'come round about eleven' is the wordplay.
'round' indicates anagramming the letters.
'about' means one lot of letters goes inside another.
'eleven' becomes 'xi' (Roman numerals).
'come' anagrammed gives 'meco'.
'meco' going around 'xi' is 'MEXICO'.
'and' acts as a link.
(Other definitions for mexico that I've seen before include "Country bordering US" , "USA's southern neighbour" , "Country south of US" , "American country gaining independence from Spain in 1810" , "Chihuahua's home" .)
