168: "agree with" versus "agree to" May 25, 2015
There are many rules in English that are not often taught, but as a
speaker people understand. The difference between "agree with" and "agree
to" is that agreement with is designated for people, for instance, "you
agreed with her" or "that borscht did not agree with me" (if you have
indigestion), whereas agreement to is designated for something nonliving
(inanimate objects and concepts).
