«والسرقة نوعان: ظاهر، وغير ظاهر»
“Poetic borrowing is of two kinds: apparent and non-apparent.”
Overt appropriation is easy to recognize because the wording or the distinctive content closely matches an earlier poet’s expression. The dependence is relatively transparent.
Concealed appropriation may lie deeper in the meaning: wording changes, the idea moves to another context, or the original line becomes a starting point for a new inference. The rhetorical and ethical evaluations of these cases need not be identical.
