Necrotronic is a 2019 film that is essentially an updated version of the original Ghostbusters. If you haven't seen it, you may enjoy it, i found it cute and entertaining in the same way.
It was an entertaining movie. I just finished watching it. It was a nice, simple distraction after spending a whole day preparing and filing my annual taxes.
*As a rule of thumb:
If the base form is spelt with a single final consonant and the final syllable is stressed, then the final… See More
consonant doubles when endings (-ing, -ed, -er, -ist etc) are added
Final -l usually always doubles in UK spelling, but generally doesn't in US spelling. There's some variation with "s" (so "busing" or "bussing" are generally both acceptable).
A complication concerns cases where the vowel in the final syllable isn't stressed, but it still carries it's "full" quality (so common candidates are "a" or "i" in a final syllable). So for example, "kidnap" would become "kidnapped". There can be variation in such cases.
Obviously, we're only talking about consonant letters that actually represent consonant sounds (so you wouldn't write "bow" -> "bowwing", for example).
*Must be why people file their taxes rather than submitting them. Though i can also see why if they were submiting them, the IRS could wonder if they might or might not be the final version.
