Groom; retinue (5)
I believe the answer is:
train
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">groom</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that groom can be written as train)</span><br/ ><br/ >'<span class="explanation-format__original">retinue</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(both can mean people following an important person)</span><br/ ><br/ ></span>
(Other definitions for train that I've seen before include "Groom" , "Locomotive or part of bride's dress" , "Succession of carriages" , "Teach (someone) a skill" , "Coach, develop" .)
