A person or entity with whom one has dealings, often implying an ongoing relationship. In computing, a client of a service.

Linguistics

Semantic Notes

Primarily denotes a buyer in a commercial transaction. Implies repeated or potential patronage, distinguishing it from a one-time 'buyer' or 'client' which can be used for professional services.

Dialectal Variation

British vs American Usage

Differences

Usage is largely identical. 'Client' is more common in BE for professional services (e.g., solicitor), while AE may use 'customer' more broadly. The term 'patron' is more formal and used for arts/restaurants in both.

Connotations

In both: neutral/commercial. Slightly impersonal compared to 'client'. Can imply 'always right' in service contexts.

Frequency

Very high frequency in both, with near-equal use.

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not confuse with 'клиент' which is closer to 'client'. 'Покупатель' is a closer direct equivalent for a retail buyer.
  • Avoid using 'заказчик' which implies 'orderer' or 'contractor'.
  • Do not translate as 'потребитель' (consumer) which is more abstract/economic.

Common Mistakes

  • Incorrect: 'I am customer of this bank.' Correct: 'I am a customer of this bank.' (article needed)
  • Incorrect plural spelling: 'costumers' (means makers of costumes).
