You are aware of how easy it can be to rank for keywords which are typos?
Now the question is, do you really want to put a misspelled keyword in your article and risk looking like an illiterate imbecile?
This would look even worse if you've invested in great content then tried to insert this misspelled keyword for SEO purposes.
An easy solution is by ranking for these keywords via Alt tags on an image.
So as an example if you have a food blog or gardening site
The correct spelling is Zucchini ( Volume: 1,000,000/mo | CPC: $0.05 | Competition: 0.03 )
But here's 3 other versions that people search for that you could use.
Zuchini
( Volume: 92,000/mo | CPC: $0.05 | Competition: 0.03 )
Zuccini
(Volume: 47,000/mo | CPC: $0.05 | Competition: 0.03 )
Zucini
( Volume: 3,700/mo | CPC: $0.05 | Competition: 0.03 )
So in the article you have an image of a Zucchini, but the alt tag might be; This is Freds award winning Zuchini
These type of keywords are ideal for branded products.
I'll use a pencil brand here, just as a very rough example
STAEDTLER
( Volume: 90,500/mo | CPC: $0.18 | Competition: 0.89 )
STEADTLER
( Volume: 8,870/mo | CPC: $0.17 | Competition: 0.86 )
So ask this company are famous for drawing supplies, a random keyword into KWFinder;
staedtler colored pencils, then misspelling it as steadtler colored pencils

These are just very basic/rough suggestions but will help people think outside the box.
