Look! Lust about George throughout lengthy period? (8)
I believe the answer is:
yearlong
'look lust about george throughout lengthy period?' is the definition.
I can't judge whether this defines the answer.
'look lust about george' is the wordplay.
'look' becomes 'lo' ('lo' is an archaic exclamation meaning 'look!').
'lust' becomes 'yearn' (I've seen this before).
'about' means one lot of letters goes inside another.
'george' becomes 'g'.
'lo' inserted inside 'yearn' is 'yearlon'.
'yearlon'+'g'='YEARLONG'
Can you help me to learn more?
(Other definitions for yearlong that I've seen before include "Lasting for 52 weeks" , "all through 1984, for example" , "Lasting 365 (or 366) days" , "throughout a period of revolution" , "Over whole 12 months" .)
