godan verb (-u), intransitive verb
all appear; be all present; all come together
Describes a situation where all expected people or things have appeared, gathered, or become available at once. Often used when a complete set is finally assembled.
メンバーが全員出そろった。
All the members have gathered.
新製品のラインナップが出そろった。
The lineup of new products is now complete.
Common kana-mixed spelling; preferred in news and everyday writing.
Kanji spelling using 揃う; less common in modern usage but still seen.
揃う means 'to be complete' or 'to be in order' without the nuance of appearing or coming out. 出揃う specifically adds the sense of emerging or becoming available.
Compound of 出 (de, 'out') and 揃う (sorou, 'to be complete'). The verb 揃う is of native Japanese origin; the exact derivation is uncertain.
