What does 練 mean in Japanese?
練 means to practise, train, or refine through repeated effort. Its most important word is 練習 (renshuu, practice) — the thing you do to get better at anything, including kanji.
The on’yomi レン appears in 練習 (practice), 訓練 (kunren, training), and 熟練 (jukuren, skill/mastery). The kun’yomi ね-る (neru) means to knead or to work something over until it is refined. The 糸 (thread) radical on the left points to its origin in refining silk.

How to Understand This Kanji
練習 (renshuu) is everyday ‘practice’ — repeating something to improve (漢字の練習, kanji practice; ピアノの練習, piano practice). 訓練 (kunren) is more formal ‘training’ or a drill, often systematic or professional (避難訓練, an evacuation drill; 訓練を受ける, to undergo training). The kun’yomi 練る (neru) literally means to knead (dough, clay) and figuratively to refine or work out (計画を練る, to work out/polish a plan). 熟練 (jukuren) is high skill built from long practice (熟練した職人, a skilled craftsman). 洗練 (senren) means refined or sophisticated (洗練されたデザイン, a polished design), and 未練 (miren) is lingering attachment or regret.

When Learners Usually See This Kanji
The word to lock in is 練習 (renshuu, practice) — pair 練 (train) + 習 (learn) and use it for practising anything: 練習する (to practise), 練習問題 (practice exercises).
Separate 練習 (renshuu) from 訓練 (kunren). 練習 is general, everyday practice to improve a skill. 訓練 is more formal, systematic training or a drill — used for professional training, emergency drills, and disciplined instruction. If it is casual self-improvement, use 練習; if it is organised or professional, 訓練 fits better.
The kun’yomi 練る (neru) is worth knowing beyond the physical ‘to knead’: 計画を練る means to carefully work out and polish a plan. This ‘refine through effort’ sense also drives 洗練 (senren, refined/sophisticated) — the same idea of something worked over until it is polished.
Summary
練 means to practise, train, or refine, anchored by 練習 (renshuu, practice). Compare it with 訓練 (formal training), and note the kun’yomi 練る (to knead / to refine a plan).
