Student or Learner
hi everyone, this is my first time using this page for help.
i don't know whether i break the rule with this post. (if does, i will delete it.)
i am the ESL, so when i was reading the definition about the word "on", i got confused
1.Used to indicate the object of an action directed, tending, or moving against it: an attack on the fortress.
with this sentence, is this the complete sentence " the object of an action which is directed, which is tending, or which is moving again it " ?
2.Used to indicate the agent or agency of a specified action:cut his foot on the broken glass; talked on the telephone.
i don't know the the meaning of the word agent and agency in this sentence.
3.Used to indicate addition or repetition: heaped error on error.
can i read this sentence as " heaped error again and again " ?
