I’ve checked these reference books and generally they’re great, but still some practical (at least for me) issues not addressed at all, some examples on the top:
1. is there any limitation on the levels of indrect quotation? eg John said Mary told David to call Peter to help Bob finish the job tonight. How many verbs like “think”, “say”, “tell”, “call” etc can appear in the same sentence before everyone get confused?
2. similiar to 1, any limitation on the levels of ownership? eg He sent the invitation to the uncle of one of his wife’s classmates…or is it better to say “his wife’s classmate’s uncle”? When to use “of” and when to use ‘s or s’? Is this more like a habit or a rule?
3. if “both first- and second-grade students” is fine, then how to split 3 and more dash-connected-word by “and”? eg
“first-, second-, and third-grade students”, or “first, second, and third-grade students”?
BTW I’m still far from making my bot chating, currently working hard to PARSE the input.
