Grammar Notes: First conditional
Original examples for study (not copied from any textbook).
1. Basic pattern
If + present idea + comma + will + result. You use this for realistic future consequences.
Example: If the tram line opens next year, the town will attract more visitors.
2. Clause order
You can put the result first: We will save time if the express train stays on schedule. No comma is needed before if when if comes second.
3. No “will” in the if-clause
Avoid if + will for a simple future condition. Say if the route opens, not if the route will open.
4. Will be able to
In the result clause, will be able to + verb often replaces can so both parts use will clearly.
Example: If the app works offline, riders will be able to check maps without Wi-Fi.
