Resembling a court; having characteristics or qualities similar to those of a royal court; styled in the manner of a court.
From 'court' + the suffix '-like' (meaning resembling or having the qualities of), creating a descriptive adjective for things that seem court-like.
The suffix '-like' is incredibly productive in English—we add it to almost any noun to mean 'resembles this thing,' which is why you can describe almost any fancy, formal behavior as 'courtlike' even if it has nothing to do with an actual court!
