I have a question about basic English usage. It would be very grateful if you could think about the question one time.
Nouns have two different forms, singular form and plural form as all English texts say. As to singular form, does "the + singular N" always imply "one N", not "more than one N"?
Peter came toward me, took me by the arm and drew me aside.
Camille tugged the ear of Sophie to punish her.
A note left in the book of a library changed the life.
I sketched the goldfish of a friend."
Are "arm", "ear", "book", "goldfish" in these sentences all "one thing" in each sentence, instead of "more than one thing", and did Peter took me by just one arm, did Camille tag just one ear of Sophie, and did I sketch just one goldfish of a friend in each sentence?
Thanks in advance.
