Questions & Answers about นักเรียน ยังไม่ ค้นคว้า ข้อมูล สำหรับ วิทยานิพนธ์ สำเร็จ ค่ะ

Why is สำเร็จ all the way at the end of the sentence, rather than right after the verb ค้นคว้า (to research)?
Resultative verbs like สำเร็จ (successfully) usually come at the end of the complete verb phrase. Here, the action being attempted isn't just "researching", it is the whole phrase "researching information for the thesis" (ค้นคว้า ข้อมูล สำหรับ วิทยานิพนธ์). So, the result word is placed at the very end to show that this entire task is what hasn't been successfully completed.
If we use ยังไม่ (not yet) before the main verb, does it mean the student hasn't even started researching?
Not necessarily! Because the resultative verb สำเร็จ is at the end of the sentence, ยังไม่ negates the success of the action, not just the action itself. It implies the student is likely already working on it, but hasn't successfully finished finding the information yet. If you left out สำเร็จ, it would sound more like they haven't started researching at all.
Why use ค้นคว้า for "research" here instead of a word like วิจัย?
วิจัย usually refers to conducting a formal academic study or the research project itself. ค้นคว้า specifically means to search deeply, investigate, or gather facts. Since the student is looking for information or data (ข้อมูล), ค้นคว้า is the perfect verb for the physical effort of digging up that information.
วิทยานิพนธ์ is a long word for a B1 learner! Does it have smaller parts to help remember it?
Yes, it is built from formal roots. วิทยา means science or knowledge (you see it in words like university, มหาวิทยาลัย), and นิพนธ์ means a written composition. Put together, it means a piece of writing about knowledge, which perfectly describes a thesis or dissertation.
