The Japanese verbal noun '修正 (しゅうせい)' means 'correction'. It refers to the act of making changes to something in order to improve or fix it. This word is commonly used in contexts such as editing documents, adjusting plans, or fixing errors. For example: I made corrections to the document「文書に修正を加えました」(ぶんしょにしゅうせいをくわえました). The plan needs correction「その計画は修正が必要です」(そのけいかくはしゅうせいがひつようです). It's important to note that '修正' implies a deliberate and often minor adjustment rather than a complete overhaul.
