The spelling of the word "sallier" can cause some confusion due to its irregularity. In IPA phonetic transcription, it is pronounced as /ˈsæ.li.ər/. The double letters "ll" and "ie" can be tricky to remember. However, this word follows the pattern of adding "-ier" to a verb stem, in this case "sally". A "sallier" is someone who sallies, or makes a sudden attack or movement. While the spelling may be uncommon, understanding the structure of the word can help with its pronunciation and meaning.
