## Senses

### 1. formal agreement

noun · CEFR C1 · Formal · Technical

Stands for Memorandum of Understanding. A written agreement between two groups that explains what they plan to do together.

For teachers: Abbreviation for Memorandum of Understanding. A non-binding agreement between two or more parties outlining the terms and details of an understanding, including each party's requirements and responsibilities.

Usage: Often used with the verb 'sign' or 'draft'; usually treated as a countable noun.

Teaching tip: In business and legal contexts, emphasize that an MOU is generally seen as a 'gentleman's agreement' rather than a legally enforceable contract.

### 2. question tag

particle · CEFR C2 · Informal · Dialect

A word used at the end of a sentence to turn a statement into a question, common in Singapore and Malaysia.

For teachers: A sentence-final particle used to form a tag question, typically seeking confirmation or expressing doubt.

- You are coming to the party tonight, mou?
- The speaker added 'mou' to the end of the instruction, effectively turning the command into a softer request for agreement.

Usage: Placed at the very end of a clause; characteristic of Singlish and Manglish.

Teaching tip: This is highly regional and informal. Advise learners that it is derived from Cantonese and is only appropriate in specific Southeast Asian social contexts.

## Examples
