The correct spelling of "more volant" is actually "more volatile". The word is pronounced as /mɔr vɒlətaɪl/. The word is derived from the Latin word "volatilis", meaning "fleeting" or "evaporating". "Volatile" can be used to describe a substance that evaporates easily or changes rapidly, or to describe a situation that is likely to change suddenly and unpredictably. It is important to use the correct spelling to avoid confusion and to ensure effective communication.
