Meaning
The kanji 字 (じ, JI) primarily means 'character', 'letter', or 'word'. It's essential for understanding written Japanese, as it refers to the individual building blocks of the writing system. This includes characters like Kanji, Hiragana, and Katakana. Beyond just 'character,' 字 can also mean 'handwriting' or even the 'style of writing' itself.
The origin of 字 has a fascinating story. It combines two simpler components: 宀 (kanmuri or ukanmuri radical), which represents a 'roof' or 'house', and 子 (ko, shi), which means 'child'. Traditionally, it's interpreted as depicting a child learning or writing characters within a home. This suggests that characters are something to be created, learned, and nurtured, much like a child.
Another perspective is that 子 (child) represents 'birthing' or 'creating.' This suggests characters are 'born' from simpler strokes or elements, or that new characters can be derived from existing ones. Whatever the precise nuance, the connection between a 'child' and a 'home' forms a memorable image. It emphasizes that 'written characters' are basic building blocks of literacy.
This kanji has 6 strokes and is taught in the 3rd grade in Japanese elementary schools, making it a relatively early kanji to learn. Despite its simple form, it holds profound importance in the Japanese language system.
Readings
The kanji 字 has both On'yomi (Chinese-derived readings) and Kun'yomi (native Japanese readings), though one is used much more often in its primary meaning of 'character' or 'letter'.
On'yomi (音読み) — Chinese-derived readings
The most common and primary On'yomi reading for 字 is ジ (JI). You'll almost exclusively hear this reading when 字 refers to a 'character,' 'letter,' 'word,' or 'handwriting' in compound words.
文字 (moji) — A very common word meaning 'character' or 'letter' in general, referring to any written symbol, including Kanji, Hiragana, and Katakana.
漢字 (kanji) — Literally 'Han characters,' these are the Chinese characters adopted into Japanese. It's an essential term for Japanese learners.
数字 (sūji) — 'Numeral' or 'figure'. Here, 字 specifically refers to numerical characters.
ローマ字 (rōmaji) — 'Roman letters', referring to the Latin alphabet.
Kun'yomi (訓読み) — Native Japanese readings
The primary Kun'yomi reading for 字 is あざ (aza). Keep in mind that when read as あざ, 字 takes on a completely different meaning, referring to a 'section of a village', 'hamlet', or 'district'. This usage is less common in everyday conversation. Japanese learners will mainly encounter it in specific place names or historical contexts. It's entirely distinct from the 'character/letter' meaning you find with the ジ reading.
大字 (ōaza) — A 'large section of a village' or 'major rural district'. You'll often find this term in official geographical designations.
小字 (koaza) — A 'small section of a village' or 'minor rural district', a subdivision of an ōaza.

Memory Tip
To remember 字, visualize its components: the 'roof' (宀) and the 'child' (子). Imagine a child sitting under a roof, perhaps at a small desk, diligently learning to write characters. The roof provides shelter, symbolizing a place of learning, growth, and creation. The child, meanwhile, represents the learner or the nascent form of something new. You can also think of characters as being 'birthed' or 'grown' from simple strokes, much like a child grows within a home. This simple story should help you solidify 字 and its core meaning in your memory.
