She gives an extraterrestrial a lot of help (5)
I believe the answer is:
ethel
'she' is the definition.
(I've seen this before)
'an extraterrestrial a lot of help' is the wordplay.
'an extraterrestrial' becomes 'et' (I've seen this in other clues).
'a lot of' means to remove the last letter (most of the word but not all of it).
'help' with its last letter removed is 'hel'.
'et'+'hel'='ETHEL'
'gives' is the link.
(Other definitions for ethel that I've seen before include "Trying not to be seen" , "- Merman, US actress" , "- Merman, US musical comedy star" , "Dame - Smyth, Eng. composer, suffragette" , "woman" .)
