Clue: Elegy gents inscribed in kazi (6)
Answer: LAMENT
Explanation: Definition: Elegy
MEN in LAT (short for latrine) Kazi is the first of several spellings given in Chambers – I would have assumed "khazi" was the main one, and that it was an Anglo-Indian word, but according to C it's "said to be from Ital. *casa*, house or *perh* Ar[abic] *kursi*, chair".
