I keep mixing up そろえる and 整える — they both seem to mean “to arrange” or “to fix,” right?

Rei

They do overlap, but the key difference is whether you’re making things uniform or making things neat and proper. Let me explain!

Both そろえる (soroeru / 揃える) and 整える (totonoeru) describe putting things in order, but they focus on completely different aspects of “order.” Mastering this difference will make your Japanese noticeably more precise.

Word	Kanji	Core Meaning
そろえる	揃える	To make uniform / To gather matching items
整える	整える	To put in proper order / To make neat and correct

TOC

そろえる (揃える): Making Things Uniform or Complete

そろえる means to align, match, complete a set, or make things uniform. The focus is on things being the same or all present. You use it when items need to match each other or when you’re gathering a complete set.

Pattern: 〜を揃える

Japanese	English
足を揃えて立つ。	Stand with your feet together (aligned).
書類を揃えてください。	Please prepare the full set of documents.
色を揃えてください。	Please match the colours.
メンバーが揃った。	All the members have gathered (the group is complete).

Key idea: the items are matching or complete as a set.

Yuka

So そろえる is about everything being the same or all being there?

Rei

Exactly! Think: shoes lined up evenly, matching chopsticks, a full set of documents. That’s そろえる territory.

整える (ととのえる): Making Things Neat, Proper, or Functional

整える means to put in order, fix up, adjust, or prepare properly. The focus is on something being in its correct state — functioning well, looking right, or following proper form.

Pattern: 〜を整える

Japanese	English
呼吸を整える。	To regulate one’s breathing.
部屋を整える。	To tidy up the room.
服装を整える。	To fix / neaten one’s attire.
体調を整える。	To get one’s health/condition in order.
環境を整える。	To set up / prepare the environment.

Key idea: things are brought to their proper, functional, or correct state.

Side-by-Side Comparison

Feature	そろえる	整える
Focus	Uniformity / completeness	Neatness / proper state
Items	Multiple same/matching items	Can be a single thing
Typical objects	Shoes, documents, team members	Breathing, room, appearance, health
Image	A matching set laid out evenly	Something restored to its correct form

Yuka

So if I’m lining up shoes at the entrance, that’s そろえる, but if I’m fixing my hair before a meeting, that’s 整える?

Rei

Perfect examples! Yes — shoes lined up (uniform set) = そろえる; hair neatened (proper state) = 整える.

Tricky Cases and Overlap

Some situations allow both words, but with different nuances:

Situation	そろえる nuance	整える nuance
本を並べる	揃える = all books matched/complete set	整える = arranged neatly in proper order
書類を準備する	揃える = all required docs present	整える = docs put in correct proper format

Common Mistakes

Wrong: 呼吸を揃える ← sounds odd; breathing doesn’t “match” anything
Right: 呼吸を整える ← regulate/fix your breathing
Wrong: メンバーが整った ← 整う suggests proper order, not completeness
Right: メンバーが揃った ← all members have gathered (complete set)
