"Subsultive" is a rare word, meaning twitching or jerking movements. Its spelling may be difficult to decipher from its pronunciation, which is /səbˈsʌltɪv/. The stress falls on the second syllable, marked by ˈ, and the word begins with the unstressed syllable /sə/. The sound /sʌlt/ rhymes with "result", while the ending /ɪv/ is pronounced like "give". It's essential to have proper phonetic transcriptions to avoid those spelling mistakes that can lead to confusion in reading and writing.
