Just like shepherd to start gathering sheep as treasure? (6)
I believe the answer is:
jewels
'just like shepherd to start gathering sheep as treasure?' is the definition.
I can't tell whether this defines the answer.
'just like shepherd to start gathering sheep' is the wordplay.
'to start' indicates taking the first letters.
'gathering' is an insertion indicator.
'sheep' becomes 'ewe' (I've seen this before).
The initial letters of 'just like shepherd' is 'jls'.
'jls' placed around 'ewe' is 'JEWELS'.
(Other definitions for jewels that I've seen before include "Finest examples" , "Gemstones" , "Diamonds, rubies, sapphires etc" , "Diamonds, rubies, emeralds etc" , "Precious stones or metals" .)
