Is shedding one lock of hair? Edward's worried (8)
I believe the answer is:
stressed
'worried' is the definition.
'is shedding one lock of hair? edward's' is the wordplay.
'shedding' indicates named letters should be taken away.
'one' becomes 'i' (Roman numeral).
'lock of hair?' becomes 'tress' (I've seen this before).
'edward' becomes 'ed'.
'is' with 'i' taken out is 's'.
's'+'tress'+'ed'='STRESSED'
(Other definitions for stressed that I've seen before include "Accentuated or strained" , "Suffering mental strain" , "Emphasized or attached importance to" , "Drew attention to" , "Accented, underlined" .)
