In short, she can make a bed (3)
I believe the answer is:
deb
'in short she' is the definition.
'Deb' can be an answer for 'she'. I am unsure of the 'in short' bit.
'make a bed' is the wordplay.
'make' indicates an anagram.
'bed' anagrammed gives 'DEB'.
'can' acts as a link.
Can you help me to learn more?
(Other definitions for deb that I've seen before include "In brief, a society girl getting out of bed" , "Girl just entering society" , "Young woman making her first appearance in society, in short" , "Young socialite" , "One coming out" .)
