Dish up; finally end with woe! (5)
I believe the answer is:
salad
'dish' is the definition.
(type of meal or dish)
'up finally end with woe' is the wordplay.
'up' says the letters should be written backwards (in down clue: letters go upwards).
'finally' indicates one should take the final letters.
'with' means one lot of letters go next to another.
'woe' becomes 'alas' (I can't explain this - if you can you should believe this answer much more).
The last letter of 'end' is 'd'.
'd'+'alas'='dalas'
'dalas' backwards is 'SALAD'.
Can you help me to learn more?
(Other definitions for salad that I've seen before include "One may well be green" , "one gets dressed" , "Cold dish of various vegetables," , "See 1 ac" , "Mixed food" .)
