Word since with cannot

User_garyCan you let me know if the above sentence is correct?

It's correct, but it needs some more information, I think. It means you cannot do this work(,) since you cut your finger [whenever you do it.] Here, 'since' means 'because' or 'as'.

User_garyI cannot do this work since I cut my finger.

I think it's potentially unclear. It could be read as meaning "I have not been able to do this work since I cut my finger" or "I cannot do this work because I have cut my finger".

LaboriousIf yes, then how can the sentence "I cannot do this work since I cut my finger" convey that meaning? I've learnt that 'since + a point in time / an event in the past' is always used with present perfe

PhilipI cut my finger yesterday, so I cannot do the work today.

GPYHowever, this rule is not strong enough to allow one to be totally confident about the intended meaning of the original sentence.

Laborious1) I cannot do this work since I cut ('cut' in the present simple tense) my finger. .

I see no way that "cut" can be interpreted as present tense in that sentence, This is because "cut my finger" cannot feasibly express a regular or continuous action. You could say "He cannot do this work since he needs constant supervision", for example.
