fuse
B2Neutral; Technical (electrical, explosives, business mergers).
Definition
Meaning
A safety device that protects an electrical circuit by melting and breaking the circuit if the current exceeds a safe level.
1. A device or component that initiates an explosive or pyrotechnic charge. 2. The act of joining or blending different elements into a single, unified whole. 3. In genetics, the union of gametes.
Linguistics
Semantic Notes
The noun and verb forms are both common. The electrical safety device sense is dominant in everyday contexts. The 'joining/blending' sense is common in abstract or business contexts (e.g., 'fuse together').
Dialectal Variation
British vs American Usage
Differences
In British English, 'fuse' can specifically refer to the cartridge containing the wire (a 'fuse wire' or 'fuse element'). In American English, 'fuse' is the general term, but the entire unit is also called a 'circuit breaker' (though technically different). For the explosive device, both use 'fuse' (US) / 'fuze' (UK technical/military spelling).
Connotations
Similar in both varieties. The 'blending' sense carries a slightly positive connotation of seamless integration.
Frequency
The electrical sense is equally high-frequency. The 'blending' sense is slightly more common in American business/media English.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Не путать с 'focus' (фокус). 'Fuse' - предохранитель/плавить. 'Focus' - сосредоточиться.
- В значении 'объединять' не всегда прямой перевод 'соединять'. Чаще 'сливать', 'интегрировать'.
- Идиома 'blow a fuse' = сильно разозлиться, а не 'перегореть' (буквально).
Common Mistakes
- Incorrect: 'The lights fused.' (Correct: 'The fuse blew' or 'The lights fused' is acceptable in UK English meaning short-circuited).
- Incorrect: 'They decided to fuse the companies into.' (Correct: '...fuse the companies' or '...fuse the companies into one entity').

FAQ
Frequently Asked Questions
Primarily the same. However, Brits might say 'the lights have fused' to mean a short circuit, while Americans would likely say 'the fuse blew'. The spelling 'fuze' for an explosive detonator is a UK technical distinction.
'Fuse' implies a more complete, inseparable blending, often involving a change in state (like melting). 'Merge' suggests a coming together where elements may still be distinguishable, like two roads or companies.
No, 'fuse' is not standardly used as an adjective. The related adjective is 'fusible' (able to be fused) or 'fused' (past participle used adjectivally, e.g., 'a fused joint').
It means to have a tendency to become angry very quickly. It metaphorically compares a person's temper to a short explosive fuse that burns to detonation rapidly.
