The word "RACT" may seem like a misspelling at first glance, but it is actually a valid word in some contexts. Its spelling can be explained using the International Phonetic Alphabet as /ræk(t)/. The "r" and "a" are pronounced as usual, but the "c" and "t" together represent a voiceless alveolar stop, as in the word "act". "RACT" is commonly used as an abbreviation for "react" or "reaction", particularly in chemistry and science contexts.
