The word "nervier" may cause confusion in terms of spelling, as it deviates from the traditional spelling of "nervous". However, the pronunciation is the same: /ˈnɜrvjər/ (ner-vee-er). The "-ier" suffix is often used to form comparative adjectives, such as "happier" or "stronger". Therefore, "nervier" could mean more nervous or anxious than usual. It's important to note that this word may not be commonly used in everyday language, but it's good to know its spelling and meaning if encountered.
