Linguistics

Semantic Notes

Primarily a term of art in chemistry and biochemistry. Its use outside of these fields (as a variant of 'laureate') is obsolete and likely to cause confusion.

Examples

By CEFR Level

B2
  • Sodium laurate is a common ingredient in some soaps.
  • The formula for this compound includes a laurate.

Learning

Memory Aids

Mnemonic

LAURate sounds like LAURel, but it's from LAURic acid. Think: 'The chemist was LAURELLED with success after synthesising sodium LAURATE.'

Conceptual Metaphor

Not applicable for the technical term.

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not confuse with 'лауреат' (laureate). The chemical term is 'лаурат'.
  • The '-ate' suffix here indicates a salt/ester, not a person.

Common Mistakes

  • Confusing it with 'laureate'.
  • Mispronouncing it as /ləˈreɪt/ (like 'lyrate').

FAQ

Frequently Asked Questions

No. 'Laurate' is a chemical term. 'Laureate' (e.g., Nobel laureate) refers to someone honoured for achievement.

From 'lauric acid', which in turn is named after the laurel tree (Laurus nobilis), as the acid was found in laurel berries.

Extremely unlikely. You might see it on a very detailed ingredients list for cosmetics or cleaning products.

As a noun, usually modified: 'The potassium laurate acted as the surfactant in the solution.'
