"Play these notes legato" marking (4)

I believe the answer is:

slur

(Other definitions for slur that I've seen before include "Slight - drawl" , "Pronounce indistinctly with each sound running into the next" , "Slight; blur" , "Contentious allegation" , "Discredit, say reputation" .)

I've seen this clue in The Washington Post.
