Turkey portion, like one given to a child (4,5)
I believe the answer is:
asia minor
'turkey portion' is the definition.
(I've seen this in another clue)
'like one given to a child' is the wordplay.
'like' becomes 'as'.
'one' becomes 'i' (Roman numeral).
'given to' means one lot of letters go next to another.
'child' becomes 'minor' (synonyms).
'as'+'i'+'a'+'minor'='ASIA MINOR'
(Other definitions for asia minor that I've seen before include "several?" , "Historical name for Anatolia" , "part of Turkey" , "was visited by early missionary" , "Historical land" .)
