[quote=RedMtl;283789]In your particular example, the difference is minimal. However, the usage is not ideal in the first example. The second is more suitable.
If by "calling" you mean to speak to a person, the comment sounds better thus: "Do not dare to address her in that manner, either in public or in private."
If you want to use "neither-nor" you can change it a bit. "Neither in public nor in private should you address her in that manner."
Usually the "neither-nor" construction is used in negative connotations. For example. "The cross-bred flower was neither tulip nor daisy." In this example, "either-or" would not work. ("The cross-bred flower was either tulip or daisy." This just is not a logical comment.)
Hi,
Seems like i felt right

, doubting the 1st sentence. To be honest, i was confused by "do not dare" standing pretty far away from the adverbial modifier that i was going "to deny".
Though if we paraphrase my examples into the one you supplied ("Neither in public...") the latter will sound a bit more formal and less natural in an everyday speech, won't it?
Anyway, thank you for your comment and looking forward to your thoughts on the above.
Regards,
Maria
