The word “definitely” is often misspelled as “definately,” as the second “i” often sounds like an “a.” However, it consists of two grammatical structures, the adjective “definite” and the suffix “-ly,” which commonly indicates adverbs. Thus, the first part of the word, representing the stem, does not change its form by adding the suffix.
