Answer:
dictionaries
Explanation:
The plural form of dictionary is dictionaries. Usually, when making an English word plural, you would add '-es' or '-s,' such as changing 'dish' to 'dish(-)es.' In order to make a word that ends in '-y' plural, though, you switch the '-y' to an '-i.' This means that, to create the plural version of dictionary, you would drop the '-y' and add '-ies.' As such, dictionary becomes dictionaries.
Therefore, the plural form of dictionary is dictionaries.
(Note: As with any language, there are, of course, exceptions to these rules and special cases are present. Also, you can always simply look up the answer to check for the plural of dictionary.)
