I'm a little stuck... Click here to teach me more about this clue!

'little rock' is the definition.
(I've seen this before)

I cannot understand how the rest of the clue works.

(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" .)

I've seen this clue in the Irish Times.
