Usage tips
Compound word
The word is made up of 'Master' (master's degree), the name of the university degree, and 'Arbeit' (work/paper). So it refers to the final paper that you write for a master's degree.
EXAMPLE
Für eine gute Masterarbeit ist eine gründliche Recherche unerlässlich.
Thorough research is essential for a good master's thesis.
Typical collocations
There are fixed verbs used around the master's thesis: you 'schreibt' (write) it, 'arbeitet an' (work on) it, 'gibt sie ab' (submit it), and it is 'betreut' (supervised) by a professor.
EXAMPLE
Ich muss meine Masterarbeit bis Ende des Monats abgeben.
I have to submit my master's thesis by the end of the month.
Sentence structure with 'über'
The topic of the master's thesis is almost always given with the preposition 'über' (about/on) and the accusative. This pattern is very common in academic contexts.
EXAMPLE
Meine Freundin schreibt ihre Masterarbeit über künstliche Intelligenz in der Medizin.
My friend is writing her master's thesis on artificial intelligence in medicine.

Masterarbeit vs Dissertation
dissertation
'Dissertation' and 'Masterarbeit' are both academic papers at a university or higher education institution. However, they belong to different degrees. You write a 'Masterarbeit' at the end of a master's degree program. You write a 'Dissertation' afterward if you want to earn a doctoral degree. Learners may confuse the words because both papers are substantial and academic. A practical question helps: Is it about the master's degree or the doctoral title?
Masterarbeit
Nach dem Praktikum beginnt Tom mit seiner Masterarbeit.
After the internship, Tom starts his master's thesis.
Dissertation
Meine Freundin arbeitet seit Monaten an ihrer Dissertation.
My friend has been working on her dissertation for months.
