（美化語）なさい - sound


The difference between （連用形）なさい and （美化語）なさい is rather clear; the first would
only be used for social inferiors, and the second can be used for social
superiors (it's also part of set expressions ごめんなさい・お休みなさい・お帰りなさい).

What I'd like to know is the implications of the second, and how it compares
to （美化語）下さい. Is it more forceful? Also, in what situations would you use the
full ～ませ forms?




お（連用形）なさい sounds more forceful and old-fashioned than お（連用形）ください and you can't
use お（連用形）なさい in general to social superiors while you can do the latter. As
for ～ませ, an employee in a shop is likely to use it to the customer.
