instruction

Compared meaning: information that tells you how to do something (noun).

比较义项：教你如何做某事的说明或指示（名词）。

• instruction 本词

  Instruction can be a firm command from someone in authority, spoken or written, and is common in formal settings like the military, exams, or manuals; often used in the singular for one step.

  instruction 可以是来自权威人士的坚定命令，可以是口头的也可以是书面的，常见于军队、考试或说明书等正式场合；常用单数形式表示一个步骤。

  The drill sergeant's instruction was simple: keep quiet and follow him closely.

  教官的指令很简单：保持安静，紧紧跟随他。

• direction

  Direction (usually plural directions) is more neutral, focused on the steps needed to complete a task or reach a place; it lacks instruction's sense of a command from an authority figure.

  direction（通常用复数 directions）语气更中性，侧重完成某项任务或到达某地所需的步骤；不带有 instruction 那种来自权威人士下达命令的意味。

  The directions for assembling the shelf were confusing and hard to follow.

  组装这个架子的说明令人困惑，很难照着做。

Both can mean information telling you how to do something. Instruction is more formal, often a command you must follow. Direction (usually plural) is more neutral, focused on steps to finish a task or reach a place. Not compared: direction's 'way' sense, instruction's 'teaching' sense.

instruction 和 direction 在“教你如何做某事的说明”这个意义上很接近，但 instruction 语气更正式、更带权威性，常指必须严格遵守的命令；direction（通常用复数 directions）语气更中性，侧重完成任务或到达某处所需的步骤。这里不比较 direction 表示“方向”的义项（如原例句中“走错方向”），也不比较 instruction 单纯表示“教学”的义项。
