When forming plurals of common nouns that end in y in English the following rules are observed:

• Common nouns ending in y preceded by a vowel form their plurals by adding s, for example, bay, bays; key, keys; toy, toys.

• Common nouns ending in y preceded by a consonant or by qu change the y to i and add es, for example, city, cities; faculty, faculties; soliloquy, soliloquies; You should accept a word from the end user and if its plural can be formed using the rules specified here you should output the word input and its plural form otherwise, you should state that the plural form of the word cannot be formed using these rules.
