Pip catching Feds out ultimately split (9)
I believe the answer is:
segmented
'split' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs can sometimes define each other.
'pip catching feds out ultimately' is the wordplay.
'pip' becomes 'seed' (I've seen this before).
'catching' means one lot of letters goes inside another.
'feds' becomes 'g-men' (I've seen this in another clue).
'out ultimately' becomes 't' (I am not sure about this - if you are sure you should believe this answer much more).
'gmen'+'t'='gment'
'seed' going around 'gment' is 'SEGMENTED'.
Can you help me to learn more?
(Other definitions for segmented that I've seen before include "Divided into parts" , "cleaved into sections" , "This bitty" , "Split into separate parts" .)
