Crossword Genius

Drilling is uninteresting (6)

Ross

I believe the answer is:

boring

I believe this clue is a double definition.

'drilling' is the first definition.
(synonyms)

'uninteresting' is the second definition.
(similar in meaning)

'is' acts as a link.

(Other definitions for boring that I've seen before include "Drilling can be tedious" , "Tedious, tiresome" , "Mentally wearying" , "like watching paint dry?" , "flat" .)
