For example, Laurel getting into another nice mess! (8)
I believe the answer is:
instance
'for example laurel' is the definition.
(I know that laurel is a type of angiospermous tree)
'getting into another nice mess' is the wordplay.
'getting into' is an insertion indicator.
'another' is an anagram indicator.
'mess' becomes 'stan' (I can't justify this - if you can you should give a lot more credence to this answer).
'nice' is an anagram of 'ince'.
'ince' placed around 'stan' is 'INSTANCE'.
Can you help me to learn more?
(Other definitions for instance that I've seen before include "A case or example of something" , "Particular case; cite" , "An insect (anag.)" , "Particular example" , "'Example, illustration (8)'" .)
