Tightening → It is formed from "tight" (from Old English "tiht", meaning firmly held) and "-ening" (a suffix indicating the process of making or becoming). The word "tightening" refers to the process of making something firm or secure.
Think of making something 'firmly held' ('tight') and the '-ening' shows it's the process of doing that. This helps you remember that tightening means to make something more secure.
