Great footballer rings guesthouse in Little Rock (6)
I believe the answer is:
pebble
'little rock' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for pebble that I've seen before include "Smooth little stone" , "Small fragment of rock" , "There are many on a stony beach" , "'Small, rounded stone (6)'" , "Small, round stone" .)
