chink

The word "chink" has several meanings, but one of them is an extremely offensive racial slur, which makes the word unusually loaded in modern English. In its neutral, older senses, it can mean a narrow opening or crack (a "chink of light" through a curtain), a small weakness (the idiom "a chink in one's armor"), or a light, sharp clinking sound (coins or glasses that chink together). However, by the 19th century it was also used as a derogatory slur for Chinese people and, more broadly, people of East Asian descent. Because that hateful meaning is so prominent, many writers avoid the word even in its literal or idiomatic senses and choose safer alternatives like "gap," "crack," "glimmer," or "clink."

The word "chink" is a small word with an outsized cultural burden. In its literal, non-people-related senses, it names something narrow and slight: a thin gap, fissure, or crack where light or air can slip through ("a chink of sunlight" in a dark room). It can also describe the act of filling those gaps—especially in older contexts—such as "chinking" the spaces between logs in a cabin to keep out wind and cold. From this physical idea comes the well-known metaphor "a chink in one's armor," meaning a small vulnerability in an otherwise strong defense.

There is also a separate, neutral sound sense: a short, light, metallic noise. Coins can chink in your pocket; glasses can chink when people toast; metal parts can chink together as you move. In this meaning, it behaves much like "clink," and the two are often interchangeable.

But the word also became a dehumanizing racial slur, especially in English-speaking countries during periods of intense anti-Chinese hostility in the 19th century, and it remains a hateful term today. Used this way, it targets Chinese people and is often extended to people of East Asian descent more generally. Because that slur meaning is widely recognized, the word can sound jarring even when a speaker intends the harmless "gap" or "clinking sound" meanings—especially in public writing or speech where context is thin.

In practice, the safest approach is simple: never use the slur sense, and consider substituting a clearer synonym in the literal and idiomatic senses ("gap," "crack," "sliver of light," "weak spot," "clink"). Understanding the word means understanding both its ordinary meanings and the harm attached to it.
