Does #1 mean #2? Are both the same in meaning? What about #3 and #4? Are both similar?
1, 3, and 4 are fine.
2 isn't used.
Both #1 and #2 convey a similar meaning, suggesting that it is not advisable to follow or obey the given advice. However, there may be a slight difference in emphasis.
#1 "You had better not follow his advice" implies a warning against blindly following or adhering to the advice being given. It suggests that the advice may not be trustworthy or beneficial.
#2 "You had better not obey his advice" emphasizes the act of obedience, implying that the advice might be authoritarian or controlling in nature. It suggests that blindly obeying the advice may not yield positive outcomes.
Similarly, both #3 and #4 convey a similar meaning, indicating that taking or accepting the given advice may not be advisable.
#3 "You had better not take his advice" suggests caution against heeding or acting upon the advice. It implies that the advice may not be helpful or could lead to negative consequences.
#4 "You had better not accept his advice" emphasizes the act of accepting the advice, implying that it might be flawed or unsound. It suggests that accepting the advice without question may not be in one's best interest.
While there are subtle differences in emphasis, all four statements essentially communicate a warning against following, obeying, taking, or accepting the given advice.
