Want expensive article no end (6)
I believe the answer is:
dearth
'want' is the definition.
(dearth is a kind of want)
'expensive article no end' is the wordplay.
'expensive' becomes 'dear' (similar in meaning).
'article' becomes 'the' (the definite article in English).
'no end' means to remove the last letter.
'the' with its final letter removed is 'th'.
'dear'+'th'='DEARTH'
(Other definitions for dearth that I've seen before include "Scarceness or lack" , "Acute shortage" , "From shortage of food" , "Scarcity - famine" , "Hatred (anag) -- shortage" .)
