💧 What exactly is 'der Leim'?

Der Leim (noun, masculine) refers to a sticky substance used to bond materials together. It's an adhesive (Klebstoff), often made from natural or synthetic raw materials. Historically, *Leim* was frequently derived from animal products (bones, skin - e.g., *Knochenleim* or bone glue), but today many synthetic glues (*synthetische Leime*) are also common.

Essentially, *Leim* is a general term for adhesives, but it's sometimes used more specifically for certain types of glue (e.g., *Holzleim* - wood glue).

🛠️ How to use 'Leim'?

Leim is mainly used in the context of crafts, construction, DIY, and industry.

Difference between 'Leim'/'Kleber'/'Klebstoff': These terms are often used interchangeably. *Klebstoff* is the most general umbrella term for adhesives. *Leim* originally referred more to natural, often water-soluble adhesives (e.g., made from starch or animal products), while *Kleber* often denotes synthetic, sometimes solvent-based products (e.g., *Sekundenkleber* - superglue, *Alleskleber* - all-purpose glue). However, in everyday language, the distinction is not always strict.

A well-known idiom is: "Jemandem auf den Leim gehen" – literally 'to walk onto the glue for someone', meaning to fall for a trick or deception.
