Greeting from hotspot, with further line conclusively appended (5,5)
I believe the answer is:
hello there
'greeting from' is the definition.
I can't tell whether this definition defines the answer.
'hotspot with further line conclusively appended' is the wordplay.
'hotspot' becomes 'hell' (a hot or fiery place).
'with' is a charade indicator (letters next to each other).
'further' becomes 'other' (synonyms).
'conclusively' suggests the final letters (the letter that concludes the word).
'appended' says to put letters next to each other.
The final letter of 'line' is 'e'.
'hell'+'other'+'e'='HELLO THERE'
Can you help me to learn more?
(Other definitions for hello there that I've seen before include "Good day" , "Hi!" .)
