be complete, uniform, all present
揃 centers on things being gathered together so that nothing is missing: a set that is complete, uniform, or all present.
揃 combines 扌 (hand) with 前 (before, front), suggesting the action of arranging things evenly or bringing them all together. The exact historical development is uncertain.
A hand 扌 arranging things in front 前 so they are all lined up and complete: nothing is missing, everything is uniform.
For セン, imagine a hand arranging a set of one hundred (百, ひゃく) items so they are all present; the sound of 千 (せん, thousand) cues セン, as if counting to make sure everything is complete.
