very small piece of material
A very small piece of a substance, like dust or dirt.
用法模式：
a particle of [substance]
常见错误：
Learners sometimes think "particle" is only a physics word. In everyday English, it is also common for very small bits of dust, dirt, or food. Also, learners may confuse "particle" with the similar-sounding word "article," which has a completely different meaning.

extremely small unit of matter
In physics, a very, very small piece of matter or energy, like an electron or proton.
用法模式：
a subatomic particle called [name]
常见错误：
Learners sometimes mix this meaning with the everyday sense of a small piece of dust or dirt. In physics, "particle" usually means a subatomic or fundamental unit like an electron, not just any small bit of material.
近义词

small grammatical function word
In grammar, a small word like "not" or "up" that helps show grammar or meaning in a phrase, but does not have a clear meaning by itself.
用法模式：
the particle [word]
常见错误：
Learners often confuse particles with prepositions because some words, like "up" or "off," can be both. In phrasal verbs, these words are usually called particles, not prepositions, because they form a single unit of meaning with the verb.
近义词
function word (A broader linguistic term that includes particles but also other items such as prepositions and conjunctions.)
|
marker (Often used in linguistics for a word or morpheme that indicates a grammatical category, similar to many particles.)
反义词
content word (Refers to words like nouns, main verbs, adjectives, and adverbs that carry clear lexical meaning, not just grammatical function.)

用法模式：

常见错误：
Learners may think this always refers to physical bits, but in this sense it describes an amount of something abstract, like evidence, truth, or doubt. It is especially common in negative phrases like "not a particle of."
近义词
