It depends on the noun. Some have -fs, some have -ves,
and some show both forms.
The ves ending is usually added to form plural nouns when a singular noun ends in -f or -fe. In these cases, the f or fe is changed to ves, such as knife to knives or leaf to leaves.
To make the singular nouns ending in f and fe plural, change f to v then add es. Examples: wife - wives thief - thieves
The only time you would add "es" to make a plural for a word ending in "f" is if the plural requires that the "f" be changed to a "v". For example: thief becomes thieves. If the "f" doesn't change, then just add "s".
The standard form for making the plural from nouns ending in -f or -fe is to drop the -f or the -fe and add -ves.Some examples are:one calf, two calvesone knife, two knivesone shelf, two shelvesone life, two livesTo form the plural for nouns ending with -ff, just add an -s to the end of the word.Some examples are:one cuff, two cuffsone cliff, two cliffsone puff, two puffsone muff, two muffs
For the majority of nouns ending in 's', add 'es' to form the plural. For example:kiss > kissesiris > irisesbusiness > businessesglass > glassesbus > busesgas > gases
Examples of nouns that end in -f or -fe that change to -ves to form the plural are:calf; calveshalf; halveshoof; hoovesknife; knivesleaf; leaveslife; livesloaf; loavesscarf; scarvesself; selvessheaf; sheavesshelf; shelvesthief; thieveswife; wiveswolf; wolves
The rule for making nouns ending an 'f' sound into the plural from is to drop off the 'f' and add 'ves'. Some examples are:calf - calvesknife - kniveslife - livessheaf - sheaveswife - wiveswolf - wolves
The usual plural form for words ending in -f or -ef is to drop the f and add ves. There are exceptions to this rule where only an s is added to the end of the words.
Nouns that end with 'f' or 'fe' are made plural by dropping the 'f' or the 'fe' and adding 'ves'. The plural for sheaf is sheaves.
