## Definition

used to introduce the first point or reason in a list. You use it when you want to organize your ideas clearly.

For teachers: used to introduce the first item in a series of points, arguments, or reasons. Often used to structure formal speech or academic writing.

## Examples

- Firstly, we need to decide on a budget.
- Firstly, the report highlights the need for better safety equipment; secondly, it suggests more training for the staff.
- Firstly, the data suggests a significant shift in consumer behavior toward sustainable products, which necessitates a complete overhaul of our current marketing strategy.

## Pitfalls

- Not "At first, I want to thank you all." but "Firstly, I want to thank you all." — Learners often use 'at first' (which means 'initially') when they intend to use 'firstly' to start a list of points.

## Usage notes

- Typically placed at the beginning of a sentence or clause to provide structural signposting.
