The correct spelling of the word is "study" - /ˈstʌdi/, not "study at chronic". "Study" is spelled with the letters "s-t-u-d-y". The first sound is /s/, followed by a short /ʌ/ sound, then a voiced /d/ sound, and finally a long /i/ sound. "Chronic" is a separate word, spelled with the letters "c-h-r-o-n-i-c". It refers to a long-term or persistent condition. It is important to be mindful of spelling to effectively communicate written messages.
