Smart Tips
Add 'please' or 'why don't you' to the command.
Use the imperative to be clear and concise.
Check if the 'will' is in the if-clause. If it is, delete it!
Try starting with the command to sound more encouraging.
Pronunciación
The Comma Pause
When the 'if' clause is first, there is a slight rising intonation at the end of the clause, followed by a brief pause.
Imperative Stress
The verb in the imperative clause usually carries the primary stress of the sentence because it is the most important action.
Condition-Command
If it rains ↗, stay inside ↘.
The rising tone shows the condition is pending; the falling tone shows the command is final.

Mnemotecnia

Story

Word Web
Desafío
Write 3 'If' rules for your house (e.g., 'If you use a cup, wash it').
Notas culturales
British speakers often add 'do' before the imperative to make it sound more like a warm invitation or a polite suggestion.
American English tends to be very direct with conditional imperatives, especially in service and safety contexts.
In corporate environments, 'please' is almost always added to soften the command, even if the speaker has authority.
The imperative mood is one of the oldest features of Indo-European languages, used for direct survival instructions. The conditional 'if' (Old English 'gif') was later paired with it to create logical contingencies.

Preguntas frecuentes (8)
Yes, `If you are tired, you should sleep` is correct and slightly softer than `If you are tired, sleep`. Both are common.
Yes, `If you're finished, you can go` is a common variation. It's a permission rather than a command.
In English, the `if` word already implies a future possibility, so adding `will` is redundant and grammatically incorrect.
It's neutral. It depends on the verb. `If you're hungry, eat` is informal. `If the alarm sounds, evacuate` is formal.
Yes! `Unless you're busy, help me` means `If you aren't busy, help me`.
The imperative is only for 'you'. For others, use `let`: `If he arrives, let him in.`
Only if the `if` clause is at the beginning. `If it rains, stay home` (Yes). `Stay home if it rains` (No).
No, that would make it a Second Conditional, which is for imaginary situations. For real commands, use the Present Simple.
