Impractically → It is formed from "im-" (meaning not) and "practicus" (from Greek "praktikos", meaning practical or relating to action) and the suffix "-ly" (meaning in a manner). The word "impractically" means in a manner that is not practical or not suited for use in real situations.
Think of 'not' ('im-') being combined with 'practical' ('practicus') to remember that 'impractically' means doing something in a way that is not practical.
