trunk
B1Neutral; formal in some technical uses (e.g., anatomy, telecommunications).
Definition
Meaning
A large, sturdy box for storing or transporting clothes and other possessions.
The main woody stem of a tree; the elongated, prehensile nose of an elephant; the torso of the human body; the main body of a motor vehicle (especially in US English); a major line of communication, transport, or supply (e.g., trunk road, telephone trunk line).
Linguistics
Semantic Notes
The word's core idea is a 'main, central, or large container/stem/line.' The meanings of 'tree stem,' 'elephant's nose,' and 'traveling box' all developed independently from the original Latin idea of 'stock' or 'stem.' This polysemy can cause confusion for learners.

Connotations
In UK, 'trunk' primarily evokes a large box for travel or storage, an elephant, or a tree. In US, the car storage sense is dominant in everyday use.
Frequency
