Learning

Memory Aids

Mnemonic

Conceptual Metaphor

SHAPE IS SOUND (in phonetics). The physical lip shape metaphorically defines the sound category.

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not confuse with 'округлить' (to round). It is the opposite process.
  • In general contexts, avoid direct translation; use 'выпрямить' (straighten) or 'расслабить' (relax) instead.

Common Mistakes

  • Using it as a general antonym for 'round' in non-technical writing (e.g., 'unround the number').
  • Confusing 'unrounded' (adjective) with 'not rounded' (phrase).
