If you've mistakenly written "sickelly" instead of the intended word, there are a few possibilities to consider. Firstly, it could be "sickly", meaning something related to illness or unwellness. Alternatively, it might be "sickly", referring to something pale, weak or fragile. Lastly, it could be a typographical error for "sickly", an uncommon word meaning excessively or overindulgently affectionate.
