Untidily → It is formed from the prefix 'un-' (meaning not) and 'tidy' (from Old English 'tidy', meaning neat or orderly) and the suffix '-ly' (meaning in a manner). The word 'untidily' means in a manner that is not neat or orderly.
Think of 'not neat' ('un-') and 'orderly' ('tidy') to remember that 'untidily' means doing something in a messy way.
