NOT SO! Unless the meaning has changed since 1991!
Webster's New World Dictionary - Third College Edition C. 1991
SICK, 2nd definition. "(sik) vt. alt. sp. of SIC2" referencing second definition of SIC "(sik) vt. sicked, sick'ing [[var. of SEEK]] 1 to set upon; pursue and attack: said esp. of or to a dog 2 to urge or insite to attack [to sic a dog on somone].
Thus, the definition of the word SICK includes in its less common use (second definition) the meaning of SIC! Have a Nice Day.
I use the Merriam Webster Collegiate, 10th Ed.
Sick is listed only as an adj., sickly is the adv., 5 meanings and variants. A variant alternate spelling is almost! acceptable.
I have never had problems with the MW including a lot of technical words. I know you can have problem with the American Heritage, original ed., because I based a spell check (c. 1984) on the official Lab dictionary and it failed to have "hotly" (15c), which was corrected in later editions, and I had to do bit of search on that one. The WNWD seems to be heavily sold but never as authoritative as MWD. (Webster is now a legal synonym for dictionary so anybody can use it.) For what this all is worth. The words are incite and someone.
That reminds of other homonym problems: cite, sight, site; seen today:incite, insight, in site; knew, new; your, you're.
And these homonym/misspellings: know, no, now; where, were, we're
