Distinguish the use of must and have to

Write the plural form of the words that end in 'f' or 'fe.' Remember that generally, you change the 'f' or 'fe' to a 'v' before adding 'es.' However, please note that NOT all words follow this rule. Be careful! There are exceptions to this rule. For the exceptions, you must just add 's.'
