For example, one in lingerie outside is a bird (5)
I believe the answer is:
eagle
'is a bird' is the definition.
(I've seen this before)
'for example one in lingerie outside' is the wordplay.
'for example' becomes 'e.g.' (short for 'exempli gratia', 'for example' in Latin).
'one' becomes 'a' (a thing is one thing).
'in' is an insertion indicator.
'outside' says to hollow out the word (remove centre letters).
'lingerie' with its centre removed is 'le'.
'eg' enclosing 'a' is 'eag'.
'eag'+'le'='EAGLE'
(Other definitions for eagle that I've seen before include "Hook-billed bird of prey -- old US $10 coin" , "two strokes fewer?" , "Bird of prey; former children's comic" , "Fine achievement on course" , "Bird of prey, may be golden" .)
