There is an interesting question in English Language Learners:
The example given is:
- Since he left the group, we have worked harder to cover his absence.
- etc. (other examples given)
This question provoked quite a reaction, which is understandable because it has the potential of being very ambiguous (with the causal being confused for the temporal meaning)
The answer there adds 'ever' in front, as in:
Ever since he left the group, we have worked harder to cover his absence.
While this is a perfectly good answer, the comment voices my question:
I notice there is much discussion following the question about the particulars of the grammar. However because this exchange is for helping English learners I believe it makes sense to provide an answer that is easy to understand and that is grammatically correct enough to sound like it came from a college-educated native English speaker. If the question were asking for a deeper answer it would have been posted on the "English Language & Usage" exchange.
Is it okay to duplicate the question here, with the idea to get more detail into what and why this happens, in a formalised Q&A?
y'know, rather than just a chat...
