I copied wind monitor as timely reminder (7,4)
I believe the answer is:
memento mori
'timely reminder' is the definition.
'memento mori' can be an answer for 'reminder' (memento mori is a kind of reminder). I am not certain of the 'timely' bit.
'i copied wind monitor' is the wordplay.
'i' becomes 'me'.
'copied' says to double the letters.
'wind' indicates anagramming the letters.
'me' duplicated is 'meme'.
'monitor' is an anagram of 'ntomori'.
'meme'+'ntomori'='MEMENTO MORI'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for memento mori that I've seen before include "Reminder of death (eg, skull) (Lat.)" , "A reminder of death's inevitability" , "skull perhaps" , "Reminder of expiry" , "Reminder that death is inevitable (Latin)" .)
