<p>How to use “hence” properly?</p>
<p>I felt ill, hence I didn’t go to school.</p>
<p>instert it in the place where you’d have normally written ‘so’ (ex: I felt ill, so I didn’t go to school).</p>
<p>it’s a conjunctive adverb</p>
<p>it’s virtually synonymous with therefore, thus, and the like.</p>
<p>don’t use it like “so.”</p>
<p>so is a coordinating conjunction and only requires a preceding comma.</p>
<p>hence, like all conjunctive adverbs, is punctuated like so:</p>
<p>…;hence,</p>
<p>…,hence,</p>
<p>at the beginning: hence,
the end: …,hence (rare)</p>
