Einzig vs. einzigartig vs. einmalig
The German words einzig, einzigartig, and einmalig all relate to the concept of one or only, but they are not interchangeable. They differ in focus: einzig emphasizes quantity, einzigartig highlights quality and incomparability, and einmalig focuses on a singular occurrence in time.
Einzig
A2The word einzig translates to only, sole, or single. It is used to express that there is just one of something, focusing purely on quantity. It answers the question how many? with the answer just one.
Er war der einzige Zeuge des Unfalls.
(He was the only witness to the accident.)
Das ist meine einzige Jacke für den Winter.
(This is my only jacket for the winter.)
Ihr einziges Ziel ist es, die Prüfung zu bestehen.
(Her sole objective is to pass the exam.)
Der einzige Unterschied ist die Farbe.
(The only difference is the color.)
Einzigartig
B1The word einzigartig means unique or one-of-a-kind. It describes something as special and incomparable due to its distinct characteristics. It emphasizes the special quality of a person, object, or concept that makes it different from all others.
Jeder Mensch ist auf seine Weise einzigartig.
(Every person is unique in their own way.)

(This handmade piece of jewelry is absolutely unique.)

(She has a one-of-a-kind sense of humor.)

(The architecture of this museum is truly unique.)
Einmalig
B1The word einmalig translates to once-in-a-lifetime, one-time, or unrepeatable. It stresses that something happens, exists, or is done only once in time. It can refer to an event, an opportunity, or a payment. Colloquially, it is also often used to mean fantastic or superb.

(Seeing the Northern Lights was a once-in-a-lifetime experience.)

Summary
In short: use einzig for the only one (a matter of quantity). Use einzigartig for something one-of-a-kind (a matter of quality). Use einmalig for a one-time event or a once-in-a-lifetime opportunity (a matter of occurrence in time). While a einmalig experience is often also einzigartig, the focus of the word is different.
