The old still agreed uni poetry needs editing (13)
I believe the answer is:
daguerreotype
'the old still' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'agreed uni poetry needs editing' is the wordplay.
'uni' becomes 'u' (U is an abbreviation for university).
'needs editing' is an anagram indicator (I've seen 'needing editing' mean this).
'agreed'+'u'+'poetry'='agreedupoetry'
'agreedupoetry' with letters rearranged gives 'DAGUERREOTYPE'.
Can you help me to learn more?
(Other definitions for daguerreotype that I've seen before include "Shot in past" , "Old photo" , "Early form of photograph" , "Eye up to regard (anag) - old photograph" .)
