One with fifty occupying beach, say, in Ibiza? (6)
I believe the answer is:
island
'in ibiza?' is the definition.
'island' can be an answer for 'ibiza?' (Ibiza is a Spanish island). I'm not sure about the 'in' bit.
'one with fifty occupying beach' is the wordplay.
'one' becomes 'i' (Roman numeral).
'with' says to put letters next to each other.
'fifty' becomes 'L' (Roman numeral).
'occupying' indicates putting letters inside (inserted letters occupy or enter the word).
'beach' becomes 'sand'.
'l' put into 'sand' is 'sland'.
'i'+'sland'='ISLAND'
'say' acts as a link.
Can you help me to learn more?
(Other definitions for island that I've seen before include "Tract surrounded by water" , "Eg, Borneo" , "Refuge as in middle of road" , "Crete, for instance" , "Water-girt territory" .)
