The words “tweak” and “tweek” are often confused, but only “tweak” is the correct and commonly used spelling when referring to making small adjustments or improvements, such as tweaking a design or settings. On the other hand, “tweek” is considered a misspelling in most contexts, though it may appear as a slang term or a name, like the character Tweek Tweak from a TV show. So, when you want to talk about minor changes or fine-tuning something, the right word to use is “tweak.”
