移り変わり・移り変り|うつりかわりutsurikawari[0]heiban (flat)

1. nounchange (e.g. season)
   青年期せいねんきは移り変うつりかわりの時期じきと見みられている。↗

   Adolescence is viewed as time of transition.

• Synonym変遷へんせんWrittenChanges things undergo over time — institutions, language, states of mind, as in 「時代の変遷」. More formal than 「移り変わり」 and typical of essays and discussion.
• Synonym変転へんてんWrittenSituations or states shifting drastically; stresses how violent the change is. 「移り変わり」 is neutral about pace — slow or rapid change both fit.
• Synonym変移へんいWrittenMeans the same as 「移り変わり」 but is formal and rare, mostly in academic papers and technical terms. In everyday speech use 「移り変わり」 or 「変化」.
• Synonym推移すいいNeutralThe course a situation takes as time passes; common with data and trends, as in 「人口の推移」. More frequent than 「移り変わり」 and keeps to objective description.
• Synonym変動へんどうNeutralFluctuation in prices, conditions and the like, as in 「物価の変動」. 「移り変わり」 is one state giving way to the next over time, not a matter of ups and downs.
• Synonym転移てんいWrittenShifting to another place, the spread of cancer, or state changes like 「相転移」 — largely a technical term. For everyday talk of change, use 「移り変わり」.
• Synonym遷移せんいWrittenUsed mainly in science and computing for state transitions or ecological succession; strongly technical. For everyday talk of seasons or eras, use 「移り変わり」.
• Synonym移ろいうつろいWrittenCovers the gradual passing of seasons and shifting of hearts, and also the slow fading of colors and light. Literary and more elegant than 「移り変わり」.
• Synonym転変てんぺんWrittenThe ever-shifting fortunes of the world; it occurs above all in the set phrase 「有為転変」. Heavily literary — for ordinary accounts of change, use 「移り変わり」.
• Related変わりかわりNeutralA change from the norm or something out of the ordinary, as in 「お変わりありませんか」. Unlike 「移り変わり」, it does not describe things succeeding one another over time.
• Related変容へんようWrittenA change in the overall look or shape of something, as in 「都市の変容」. 「移り変わり」 instead stresses things succeeding one another over time.
• Related移りうつりNeutralA shift from one state to another, but rarely used alone; also a gift tucked inside a returned container. For change over time, say 「移り変わり」.
• Related転換てんかんNeutralA switch in policy or direction, as in 「方針転換」. 「移り変わり」 is change unfolding over time, slow or sudden, and carries no sense of a deliberate turn.
• Related変革へんかくWrittenRoot-and-branch change to institutions or society, usually implying deliberate reform. 「移り変わり」 is simply change over time, with no hint of innovation.
• Related過渡かとWrittenThe in-between stage while something moves from old to new; mostly seen in 「過渡期」 and 「過渡的」. 「移り変わり」 names the changing itself, not a phase.
• Related変質へんしつNeutralA change in the nature or quality of something, often for the worse, as in 「変質した食品」. 「移り変わり」 speaks only of succession, with no judgment of good or bad.
• Related移行いこうWrittenA move from one state to another — institutions, systems, workflows. 「移り変わり」 leans toward change that happens naturally over time.
• Related変わりようかわりようNeutralThe way or degree something has changed, as in 「その変わりようには驚いた」. It dwells on how drastic the change is, not on the ongoing succession 「移り変わり」 describes.
• Related変易へんえきWrittenChange or alteration, also used for making something change. Extremely formal and almost never heard in daily life; say 「変化」 or 「移り変わり」 instead.
• Antonym不変ふへんWrittenEternally unchanging, as in 「不変の真理」. It stands at the opposite pole from 「移り変わり」 on the axis of change versus constancy.
• Antonym静止せいしNeutralStanding still, without movement — the opposite of the flowing change of 「移り変わり」, on the axis of motion versus stillness. Common in physics and for still images.

For the passing of seasons or eras over time, 「移り変わり」 is the default, as in 「季節の移り変わり」. In essays and discussion pick 「変遷」, for data and trends 「推移」, for a literary tone 「移ろい」. 「転換」 and 「移行」 are switches of direction or state, 「変革」 deliberate reform, 「変動」 fluctuations, 「変質」 change in nature, 「変容」 a changed overall look. 「変転」 stresses drastic shifts, 「過渡」 the in-between stage, and 「遷移」「転移」「変移」「変易」 are technical or rare. 「変わり」 and 「変わりよう」 are ordinary change, not succession; the antonyms are 「不変」 and 「静止」.
