My own rule on spelling!

I have come up with a spelling rule, based on phonetics, and would like you to either prove or refute it.
1. We usually change ie to ying when adding ing only if the verb is one syllable, since the final sound is [ai], e.g.: vie - vieing.
Here's the rule: But if the verb is a more-syllable verb, we just add ing (because the final sound is ), e.g.: stymie - stymieing.

Apart from stymie, how many other multisyllabic verbs can you find that end with -ie?

Do you mean "vie - vying"?

There are only three other single-syllable verbs ending with "ie", in any case.

I've been trying to think of more. There's hogtie, for one, which doesn't follow the OP's rule. It's derived from "tie" but is still a multisyllable word.
