My Flashcards

Definition

Meaning

The essential parts of a vehicle that enable it to move, including wheels, axles, suspension, and transmission.

In informal use, clothing or equipment designed for running or athletic activity. In machinery, the moving parts of a device or system that allow it to operate.

Linguistics

Semantic Notes

Primarily a compound noun. In transport/automotive contexts, it is a fixed technical term. The athletic sense is a more recent informal extension where 'gear' takes its 'clothing/equipment' meaning.

Dialectal Variation

British vs American Usage

Differences

Both dialects use the term in automotive contexts identically. The athletic/clothing sense may be slightly more common in American marketing/lay usage.

Connotations

In both, the automotive sense is technical and precise. The athletic sense is casual and consumer-oriented.

Frequency

Low frequency in general conversation, but standard within specific technical fields like automotive repair, rail transport, and military logistics.

Learning

Memory Aids

Mnemonic

Think of a car 'running' down the road. The 'gear' that makes that 'running' possible (wheels, axles) is the running gear.

Conceptual Metaphor

FOUNDATION FOR MOVEMENT (The parts are the essential foundation that enables motion, much like legs are for a person).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid translating literally as 'бегущее снаряжение'. For vehicles, use 'ходовая часть'. For athletic clothes, use 'экипировка для бега'.

Common Mistakes

  • Using it to mean 'operating a piece of gear' (gerund + noun). Confusing it with 'running shoes' only in the athletic sense.

FAQ

Frequently Asked Questions

No. While its primary and most specific meaning is vehicular, it is also used informally for athletic clothing and equipment for running.

No. The engine is the power source. Running gear refers to the components that transfer that power into motion and support the vehicle (wheels, axles, suspension, etc.).

Yes, it is applicable. A bicycle's running gear would include the wheels, tyres, chain, gears, pedals, and brakes—the parts that make it roll and are subject to wear.

It is formal and technical in engineering/automotive contexts. It becomes informal when referring to athletic apparel.
