what is the meaning of undefined in the following sentence? the edges of the image were blurry and undefined.
undefined is a quality of being seen.
undefined means becoming noticeable.
undefined means not clear or defined.

Explanation:

The prefix "un - " means "not". The word "defined" means "clear or having a specific meaning". Combining them, "undefined" means "not clear or defined". In the context of the sentence "The edges of the image were blurry and undefined", since "blurry" implies a lack of clarity, "undefined" (with its "un - " prefix negating "defined") logically follows to mean "not clear or defined".

Answer:

Undefined means not clear or defined.
