This question raised when a colleague told me that the correct way of writing bully + -ing is bullying, rather than bulling.
Initially I thought that the -y- should be kept only when the verb ended with in consonant-vowel-consonant. My assumption was based on the verbs enjoy and say whose present-participle forms are enjoying and saying.
However, some time later I realized there were other verbs, not ending in consonant-vowel-consonant, that kept the -y-, such as studying, applying, crying and trying...
Currently, I imagine there is no such grammar rule and I mixed the plural rules with verb rules. Nevertheless I'd like to get a confirmation. Can anyone help me clarify (another example: clarifying) that?
