side

Compared meaning: located at, or moving toward, the side (adjective).

比较义项：侧面的（形容词）。

• side 本词

  Side is a common, everyday adjective placed before a noun (side door, side street, side effect); it simply marks position next to or from the side, with no formal or technical tone.

  side是日常表达中常用的形容词，通常放在名词前（如side door侧门、side street小巷、side effect副作用），只是表示位置“在旁边”或“从侧面”，没有正式或专业的语气。

  We entered through the side door to avoid the crowd at the front.

  我们从侧门进去，以避开前门的人群。

• lateral

  Lateral is a more formal or technical word used mainly in science, medicine, sports and business contexts (lateral pass, lateral movement, lateral thinking); it stresses sideways direction rather than mere position.

  lateral是较正式或专业的词，主要用于科学、医学、体育和商务语境（如lateral pass横传、lateral movement侧向移动、lateral thinking横向思维），强调“向侧面”的方向，而不仅仅是位置。

  The coach asked the players to practice a quick lateral pass.

  教练要求球员们练习快速横传。

Side and lateral can both mean at or toward the side. Side is a common adjective, as in side door or side street, with no formal tone. Lateral is more formal, used in science, sports, or business, as in lateral pass. Not compared: side (noun).

这两个词在“侧面的”这一义项上意思相近，但语域不同：side是日常用语，常见于side door（侧门）、side street（小巷）等搭配；lateral则较为正式或专业，多用于科学、医学、体育等领域，如lateral pass（横传）。这里不比较side用作名词表示“一边、一侧”的用法。
