I'm doing a research on English modality (for reference I'm using F.R. Palmer's book "Modality and the English Modals").
In the book the author distinguishes between the three kinds of modality:
Epistemic modality (for possibility)
Deontic (for permission and obligation)
Dynamic (subject oriented "modality" i.e. objective potential)
To test the practical application of the theoretical points given in this book, I turn to native speakers' aid, but the issue is that everyone appears to have their own interpretations of modality in what seems to be the same context (some might understand a modal to be deontic (e.g. you have my permission to do that), while others understand it as dynamic (there is an objective possibility to do that).
To have a better understanding of what I mean, please, take a look at my thread on wordreference.com (particularly at the post #8, where I give a link to yet another one of my posts).
Only few people accepted the use of "can" there, but here (#1, Ex. 4) a similar example was validated:
There seems to be some misconception at play. This might be due to the fact that when we acquire language as children, we absorb it intuitively with no instructions. The language doesn't come in a package together with a user guide like a table from IKEA or some exhaustive grammar book explaining how our mind generates grammar. There's nothing to language but the language, so oftentimes we have to base our inferences on intuition. My objective here is to understand whether "can" is indeed not used to denote objective future possiby or is it just that the native speakers preceive "can" in my examples to be something else (e.g. permission or epistemic possibility).
Could you, please, check if my assumptions about the meaning of "can" in the following sentences are correct. If they are not, how would you interpret them?
A: What is this bank good for?! We all are jobless!
B: When Barclays opens a branch in our town, you [can / will be able to] apply for a job there ("B" merely states a fact about future possibility; "to be able to" is more naural here).
A: I need to find a job.
B: When Barclays opens a branch in our town, you can apply for a job there ("B" suggests a solution; in such situations "can" looks better. In the book this use of "can" is titled as "implication").
Thank you in advance!
