• sticky

  Describes a surface or object coated with a substance that sticks to skin or other things; informal, sensory, often mildly unpleasant (jam, sap, sweat).

  描述表面或物体沾上一种会粘住皮肤或其他东西的物质；口语化、强调触感，常带轻微不悦的意味（如果酱、树脂、汗水）。

• adhesive 本词

  Describes a material's or product's ability to bond firmly to a surface; more formal and technical, typically describing glue, tape or other bonding products.

  描述材料或产品能牢固粘附在表面上的能力；较正式、专业，通常用来形容胶水、胶带等粘合产品。

  He used strong adhesive to stick the broken handle back together.

  他用了强力粘合剂把断裂的把手重新粘在一起。

Both describe something that sticks, but sticky means a surface coated with something clingy, often unpleasant, and sounds casual. Adhesive describes a material's ability to bond firmly, like glue or tape, and sounds formal. Sticky can also mean a difficult situation, not compared here.

sticky 强调物体表面沾上粘性物质、摸起来发粘的触感，语气较口语化，常带轻微不悦的意味；adhesive 强调材料或产品本身具有牢固粘合的能力，语气更正式、专业，多用于描述胶水、胶带等产品。这里不比较 sticky 表示“棘手的（情况）”的引申义。
