<p>I fear this thread is not very exciting.</p>
<p>But calling all grammar nerds:</p>
<p>Is correct usage of parallel as a verb
“to parallel x to y”
or
“to parallel x and y?”</p>
<p>I’m not speaking on any authority here, but I’d go with the second simply because it sounds slightly better to my ears and places the two elements on the same level, so to speak. I’m sure they’re both commonly used, though.</p>
<p>But really, the easiest way out of this would be to use another word (“parallel” => “compare”) or sentence construction. Even a change as simple as “to parallel the two ______” would make the phrase less awkward.</p>
<p>neither .</p>
