Formally
“Formally” 是副词，表示以正式、合乎礼仪或官方程序的方式行事。与 “formerly”（以前）发音相近但含义不同，需注意区分。
- “The agreement was formally signed at the ceremony.” (协议在仪式上正式签署。)
- “Guests were formally invited by written invitation.” (宾客收到书面邀请函正式受邀。)
- “She was formally trained as a classical pianist.” (她接受过正规的古典钢琴训练。)
“Formal” 来自拉丁语 “formalis”，与 “forma”（形式、形态）相关，强调符合既定形式与规范。
词根 “formal” 表示正式的；副词后缀 “-ly” 表示“以……方式”。
外交与商务场合 “formally announce” 强调官方发布；学术语境 “formally educated” 指受过系统正规教育。
- 形容词: formal
- 名词: form, formality
- 易混词: formerly（以前）
- 固定搭配: “formally invited” (正式邀请), “formally announced” (正式宣布), “formally dressed” (着装正式)
“formal” 正式 + “-ly” 地——formally 就是正式地；别和 formerly（以前）搞混。
“The couple was formally introduced at the banquet before giving their speeches.” (这对夫妇在宴会上被正式介绍，随后发表了致辞。)
