Lived in Iowa somewhere (3)
I believe the answer is:
was
'lived' is the definition.
('be' can be a synonym of 'live')
'in iowa somewhere' is the wordplay.
'in' indicates the answer is hidden within the clue.
'WAS' is hidden within 'iowa somewhere'.
(Other definitions for was that I've seen before include "Lived" , "Existed in the past" , "(He/she) existed" , "(I/he/she/it) existed" , "'Is, in the past (3)'" .)
