Question

I read the book since morning correct tense​

Answer 1

I have been reading the book since morning.

• When we use since, two types of tense can be used, either present perfect tense or present perfect continuous tense. This depends on the continuous nature of the action.
• When, there's no ending point of an action, we mostly used present perfect continuous tense to show that the action is still occurring in the present also.
• In this way, we have employed present perfect continuous tense in the given sentence to rectify it.
