盐 🔊

网络内容摘要 (Web Content Summary):

盐（拼音：yán，偶见音yàn）是常用汉字，表示“食盐”，也泛指各种盐类化合物。 盐 (yán, yàn) is a common Chinese character meaning "table salt" and, more generally, chemical salts.

• 核心含义与化学用法： “盐”最初指日常食用的食盐（氯化钠），如今也指由金属离子或铵根离子与酸根或非金属离子结合构成的化合物。 Core meaning & chemical use: Initially referred to edible salt (sodium chloride), and now also means ionic compounds formed from metals/ammonium with acid/non-metal ions (salts) in chemistry.
• 字形与起源： “盐”始于战国金文，古字采用“鹵”（咸味的意思）作意旁，“监”作声旁。据传，古人“宿沙”最早发明用煮海水制盐。 Origin: First found in Warring States inscriptions, the character uses “鹵” (meaning salty) for meaning and “监” for sound. Legend says “Su Sha” first invented sea salt extraction.
• 特别用法与读音： 作名词时多读“yán”，偶用于“用盐腌制”时读“yàn”（较罕见）。“盐”也可作姓氏。 Special usage/pronunciation: Usually pronounced “yán” as a noun; “yàn” (rare) denotes “to salt/pickle.” “盐” can also be a surname.
• 易混淆点： “盐”与“咸”是近义词，但“盐”更偏指物质本身，“咸”侧重味道。 Common confusion: “盐” refers to the substance, while “咸” describes the taste (salty).
• 常用词/成语： 常见搭配如“食盐”、成语如“言必有中（与‘盐’无直接关系）”未见直接成语；但许多和“盐”相关的字如“盐水”、“盐碱地”等在现实生活中常见。 Common words/phrases: Frequent collocations include “食盐” (table salt), “盐水” (saline), “盐碱地” (alkali soil), etc. There are no notable idioms directly using “盐.”
