Present participle of the verb "charade"

How do you spell the present participle of the verb “charade?” Is it “charading” or charadeing?"

Hi,

If it exists and I haven’t heard of it, there would be no ‘e’.

Thanks for the response, Alan. I think that you are correct. Concerning whether or not it exists: cannot a participle be formed from all verbs?

I’ve actually heard it. Alan’s correct that the e is dropped.

When forming present participles and gerunds the original pronunciation is always maintained. In charade the silent ‘e’ at the end is used to make the ‘a’ in the second syllabe into the ‘long a’ sound /e/.

One of the rules of English phonology is that a vowel preceding a single consonant followed by another vowel is always long. When -ing is appended to charad- the ‘e’ is no longer needed to maintain the long a sound because ‘i’ now follows the single consonant ‘d’.

Wow! Thanks Oxford Blues for the extensive explanation.
