Tall bird lit up in street (5)
I believe the answer is:
stilt
'tall bird' is the definition.
'stilt' can be an answer for 'bird' (stilt is a kind of bird). I am not sure about the 'tall' bit.
'lit up in street' is the wordplay.
'up' indicates anagramming the letters (letters get chucked up).
'in' is an insertion indicator.
'street' becomes 'st' (abbreviation).
'lit' with letters rearranged gives 'til'.
'til' inserted into 'st' is 'STILT'.
Can you help me to learn more?
(Other definitions for stilt that I've seen before include "Aid for walking tall" , "Walking pole; wader" , "Wading bird; post" , "laboured and unnatural in the past" , "gets one member off the ground" .)
