cart, trolley 
[noun]
[de kar, de kar-ren]

The word "kar" or the diminutive "karretje" is typically use for relatively small carts or trolleys (shopping, luggage, golf). Bigger carts that are more like wagons can be called a "kar" but are also often called a "wagen". "Wagentje" and "karretje" are more or less interchangeable. "Kar" is also used informally for a "car (automobile)" with the associated verb "karren".

Examples:
- "Pak jij even een boodschappenkarretje, een mandje is niet voldoende denk ik." 
("Will you get us a shopping cart, I don't think a basket will suffice.")

- "Wow, wat een gave kar!!" 
("Wow, what a cool car!!")

- "Man, wat is deze koffer zwaar!" – "Waarom pak je dan geen bagagekarretje sukkel!" 
("Man, this suitcase is heavy!" – "Then why don't you get a luggage trolley you fool!")

Expressions:
- "De kar trekken": used figuratively for "to lead the effort".

Example:
- "Dit project schiet voor geen meter op!" – "Ja, dat heb je als Frank de kar trekt."
("This project is not progressing one bit!" – "Yup, that's what you get when Frank is leading the effort.")

Related words:
- Karren: to drive [verb, informal] [karde, gekard].

Example:
- "Morgen pakken we onze tassen in en overmorgen karren we naar Zuid-Frankrijk." 
("Tomorrow we'll pack our bags and the day after tomorrow we'll drive to the south of France.")
