Finally, you love scrambled egg! (5)
I believe the answer is:
ovule
'egg' is the definition.
(thesaurus)
'finally you love scrambled' is the wordplay.
'finally' suggests the final letters.
'scrambled' indicates anagramming the letters.
The final letter of 'you' is 'u'.
'u'+'love'='ulove'
'ulove' with letters rearranged gives 'OVULE'.
(Other definitions for ovule that I've seen before include "Part of plant ovary which becomes seed" , "Egg cell" , "Part of seed plants" , "Undeveloped seed" , "Part of flower" .)
