Meaning
The N1 kanji 迭 (てつ) signifies alternation, succession, or rotation. This character describes how people, things, or events replace one another in a systematic sequence, taking turns or following a specific order. Unlike a simple, one-off replacement—such as swapping one item for another—迭 often implies a cyclical, continuous, or ordered change. One entity departs, and another arrives to take its place. This often includes the understanding that the first, or something similar, might return later in the sequence or cycle.
Etymologically, 迭’s meaning is deeply rooted in its structure. It's classified as a phono-semantic compound (形声文字, keisei moji), composed of two main elements. The left side features the radical 辵 (shinnyō), symbolizing "walk," "movement," or "a path." This radical immediately brings to mind progression, passing by, or a journey. The right side is 矢 (ya), meaning "arrow." While 矢 functions primarily as a phonetic element (indicating the sound "tetsu" or "chi"), it also strongly resembles 失 (shitsu), meaning "to lose" or "to miss." This unique combination can be interpreted as a "movement" (辵) where something is "lost" or "missed" (失) from its original spot, thereby making way for something new. This imagery clearly illustrates the dynamic of one thing moving out, allowing another to move in. It establishes a sequence of turns or an alternation.
Visually, the flowing lines of the 辵 radical on the left side evoke an ongoing journey or continuous passage, signifying progression. The right component, reminiscent of 失, conveys the idea of something being relinquished or giving way, allowing something else to succeed it. Together, these elements paint a clear picture of dynamic, ordered replacement. This kanji is often found in formal, academic, or journalistic contexts. It's particularly useful when discussing political changes, natural phenomena, or structured sequences of events.
The kanji 迭 has 8 strokes. It is not part of the standard Joyo Kanji list but is classified at the N1 level, indicating its advanced usage and its common appearance in specialized vocabulary encountered in higher-level Japanese texts.
Readings
On'yomi (音読み) — Chinese-derived readings
On'yomi are readings that originate from Chinese. For 迭, the primary on'yomi are テツ and チツ, with テツ being considerably more common in contemporary Japanese usage.
テツ (TETSU): This is the most frequently encountered on'yomi for 迭. It appears in numerous compound words that describe changes, successions, or repeated occurrences in a systematic manner.
更迭 (kōtetsu) — personnel change; reshuffle. This term is widely used in political, governmental, or corporate environments when leaders or officials are replaced, often implying a formal succession rather than merely a dismissal.
迭出 (tesshutsu) — appearing in succession; emerging one after another. This describes multiple instances, events, or phenomena occurring sequentially.
交迭 (kōtetsu) — alternation; rotation; taking turns. Refers to a process where two or more things regularly succeed one another in a pattern.
迭次 (tetsuji) — in succession; in order; one after another. This is the standard modern reading.
チツ (CHITSU): This reading is less common than テツ and tends to be found in more classical or specialized terminology, or occasionally as an alternative reading for compounds that predominantly use テツ.
輪迭 (rinchitsu) — rotation; turning in succession. A more literary or archaic term describing a cyclical, sequential rotation.
交迭 (kōchitsu) — alternation; rotation (an alternative reading for 交迭). While こうてつ is the dominant pronunciation, こうちつ may occasionally be encountered in older texts or specific contexts.
迭次 (chitsuji) — in succession; in order; one after another (sometimes found in older or more academic texts, though てつじ is the standard modern reading).
Kun'yomi (訓読み) — Native Japanese readings
The kanji 迭 does not possess any commonly used kun'yomi (native Japanese readings) as a standalone verb, adjective, or noun. Its usage is almost exclusively confined to on'yomi compounds, making it a character primarily encountered in formal or academic vocabulary rather than in everyday conversational Japanese where native verbs or adjectives would be preferred for similar concepts.

Memory Tip
To easily remember 迭, break it down into its components and create a short story. The left side is the radical 辵 (shinnyō), which means "movement" or "walking along a path." The right side is 矢 (ya), meaning "arrow." Importantly, 矢 also strongly hints at 失 (shitsu), meaning "to lose" or "to miss." Picture objects moving along a designated path (辵). As each object proceeds, it eventually loses (失) its current position by moving past it, allowing the next one in line to take its turn. This continuous movement—where one entity yields its place to another—vividly illustrates the core meaning of alternation or succession. Alternatively, you might imagine a series of arrows (矢) flying sequentially along a path, each arrow replacing the one before it in a specific spot. This shows an orderly replacement.
