very large array
Low (Technical/Specialized)Technical/Scientific (Astronomy)
Definition
Meaning
A radio astronomy observatory consisting of many individual dish antennas arranged in a specific pattern, working together as a single instrument.
The term can be used more generally in technical contexts (e.g., computing, data science) to denote any extensive or massive collection or arrangement of similar components, though this is less common. Its primary and defining use remains the astronomical facility.
Linguistics
Semantic Notes
Always refers to the specific facility when capitalized (Very Large Array or VLA). In lowercase, it may refer generically to a large arrangement of items but is rare. The term is a proper noun referring to a single, specific instrument.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning. The VLA is a specific US facility, so the term is more frequent in American English in its proper noun sense.
Connotations
Primarily associated with the US National Radio Astronomy Observatory's facility in New Mexico. In British English, it is a known technical term but less culturally embedded.
Frequency
Higher frequency in American English due to the location of the facility. In British English, more likely to be used by specialists.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'array' as 'массив' in the computing sense; here it is 'антенная решётка' or 'система антенн'.
- Do not confuse with 'very big number/quantity' (очень большое количество). It is a specific physical system.
Common Mistakes
- Using it as a common noun for any large collection (e.g., 'a very large array of books').
- Not capitalizing when referring to the specific observatory (should be 'Very Large Array').
- Confusing it with other telescope arrays like ALMA or the SKA.
