جِئْتُ لِطَلَبِ الْعِلْمِ
Translation: I came to seek knowledge.
جِئْتُ: past verb and first-person subject.
لِـ: causal preposition.
طَلَبِ: genitive noun after lām, first term of iḍāfa.
الْعِلْمِ: genitive second term.
Added teaching example: here ṭalabi is not accusative, because an overt lām governs it.
