To Arrange Something, To Collect Something, To Align Something
transitive verb, ichidan verb
Remember 揃う, "to be complete"? This is the transitive version of that, and it means things like to arrange something, to gather something, and to align something. This one is a little tricky to understand and translate well. At its core, this verb describes the act of arranging all of the necessary things for something. But it can also describe aligning certain things in a uniform, matching manner. If this still isn't clear, have a careful look at our context sentences and collocations!
