Mean parents finally going to hospital with sick baby (6)
I believe the answer is:
shabby
'mean' is the definition.
(thesaurus)
'parents finally going to hospital with sick baby' is the wordplay.
'finally' suggests the final letters.
'going to' says to put letters next to each other.
'hospital' becomes 'h' (abbreviation for hospital on maps).
'with' means one lot of letters go next to another.
'sick' is an anagram indicator.
The last letter of 'parents' is 's'.
'baby' anagrammed gives 'abby'.
's'+'h'+'abby'='SHABBY'
(Other definitions for shabby that I've seen before include "Worn and run-down, like clothes" , "Frayed" , "Badly clad - sort of trick?" , "Ragged - mean" , "Ill-dressed - mean" .)
