由 (yóu)  is used to emphasize who is the doer or initiator of an action, a bit like in English where we might say: "Andy ''is the one who...." 

==Structure==

<div class="jiegou">
Topic + 由 + Person + Verb
</div>

==Examples==

<div class="liju">
* 这 件 事 <em>由</em> 我 负责。<span class="trans">I am responsible for this.</span>
* 这 是 <em>由</em> 他 决定 的，你 就别 干涉 了。<span class="trans">This is for him to decide, don't meddle.</span>
* 太 悲剧 了，会议 <em>由</em> 王总 主持，肯定 会 很 无聊！<span class="trans">Oh no. This meeting is being led by the head manager. It's definitely going to be boring.</span>
</div>
