Appear again about old dog getting cold (7)
I believe the answer is:
reoccur
'appear again' is the definition.
Both the answer and definition are verbs in their base form.
Perhaps they are linked in a way I don't understand?
'about old dog getting cold' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'dog' becomes 'cur' (a cur is an aggressive or scruffy dog).
'getting' says to put letters next to each other.
'cold' becomes 'C' (eg on taps).
'cur' after 'c' is 'ccur'.
're'+'o'+'ccur'='REOCCUR'
Can you help me to learn more?
(Other definitions for reoccur that I've seen before include "make comeback" , "Come again?" , "Happen again" .)
