## Senses

### 1. by the way

adverb · CEFR B1 · Informal · Slang

Stands for By The Way. Use this when you want to add a quick thought or extra information to a conversation.

For teachers: Abbreviation for By The Way. Functions as a discourse marker to introduce incidental information or a shift in topic.

- I'll see you at the party tonight. BTW, do I need to bring any snacks?
- The meeting has been moved to Room 4. BTW, did you ever receive that updated spreadsheet from the accounting department?

Usage: Usually placed at the beginning or end of a sentence in digital messaging.

Teaching tip: While common in texts and social media, students should be warned that using this in professional emails can appear unprofessional or lazy.

### 2. between

preposition · CEFR C1 · Technical · Informal

A short way of writing the word 'between'.

For teachers: Abbreviation for Between. Used occasionally in technical notes, shorthand, or informal lists to indicate a middle position or range.

- The data shows a significant correlation BTW the two variables, though further testing is required to confirm the cause.

Usage: Rarely used in prose; mostly found in personal notes or informal schedules.

- I'm heading to the store now; BTW, do we need more milk for tomorrow?
