See Mark's predicament (4)
I believe the answer is:
spot
I believe this clue is a triple definition!
'see' is the first definition.
(to spot is to notice or catch sight of)
'mark's' is the second definition.
(spotting is a kind of marking)
'predicament' is the third definition.
(I've seen this before)
(Other definitions for spot that I've seen before include "Blob" , "See; place" , "Drop of rain" , "Informally, catch sight of" , "Place - zit" .)
