Hardly welcoming (4)
I believe the answer is:
cold
'hardly welcoming' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cold that I've seen before include "Lacking emotion" , "Chilly; unemotional" , "Unemotional; wintry" , "Glacial" , "Chilly; minor ailment" .)
