Lies bobbing like a speck in the ocean (4)
I believe the answer is:
isle
'a speck in the ocean' is the definition.
(I've seen this in another clue)
'lies bobbing' is the wordplay.
'lies' can be anagrammed to 'ISLE'.
However, I'm not clear how the anagram is indicated.
'like' acts as a link.
Can you help me to learn more?
(Other definitions for isle that I've seen before include "man with capital?" , "This is sceptred!" , "Man's one" , "Small area of ground" , "I shall hear" .)
