  half  halves
  leaf  leaves

In addition, the following nouns ending in fe form the plural by changing the f to v and adding s:

Singular  Plural
  knife                                                                                                       knives
  life  lives
  wife  wives

There are also a few nouns ending in f which can form the plural in two different ways. For example:

Singular         Plural
  hoof                                                                                                     hoofs or hooves
  scarf  scarfs or scarves

d. Nouns ending in 'O'

Some English nouns ending in o form the plural by adding s, some form the plural by adding es, and some can form the plural by adding either s or es. The following fairly commonly used nouns form the plural by adding es:

Most other nouns ending in o, particularly those of Spanish or Italian origin, can form the plural simply by adding s; however a good dictionary should be consulted in cases of doubt. For example:
