Hello,<br/><br/>1. We use a much more precise definition .....<br/><br/>Here |"precise " is an adjective, "more precise" comparative degree of "precise".<br/><br/>Why "much" has been used here?<br/><br/>I am not able to understand the construction like " much more ...'.<br/><br/>Would any one here explain it?<br/><br/>Thanks.
