Can blurred be used as present tense?

dirty
partially-obscured
scratched
dirt-streaked
dirt-smeared
dark

"Blurred" is not so good, because it refers to the image and not the window imho.

Blurred is an adjective; they don't have tenses.

It often strikes me Lis how often we encounter concepts for which there's no single common word

As for Con's comment, as a technician or grammaticist of course he's right. But here's another case of missing word. There ought to be a term for an implied tense, eg, "I lie on my mother's lap" instantly bringing to mind past instances

I didn't like to say too much about that. Technicalities can make you tense.

Yea Mac, while they probably number in the tenses
