Meaning and Definition
A trailer without a front axle, designed to be attached to and supported by a tractor unit (truck cab).
The combination of a tractor unit and a semitrailer forms an articulated lorry (UK) or semi-truck (US). The term can also refer to the cargo-carrying unit itself in logistics and transport contexts.
Dialectal Variation
British vs American Usage
Differences
In British English, the full vehicle is typically called an 'articulated lorry' or 'artic'. The term 'semitrailer' is used for the trailer part. In American English, the full vehicle is a 'semi-truck', 'tractor-trailer', or simply 'semi', with 'semitrailer' referring to the trailer.
Connotations
In both varieties, the term is neutral and technical. In AmE, 'semi' as a standalone noun is very common in informal contexts.
Frequency
More frequent in American English due to the prominence of road freight. In British English, 'articulated lorry' and its abbreviation 'artic' are more common in general discourse.
