Understanding the Subtle Differences Between 'If Possible' and 'When Possible'

In professional and everyday communication, the phrases 'if possible' and 'when possible' are often used, but they carry different connotations and implications. This article aims to clarify these differences and provide clarity on when to use each phrase effectively.

General Overview

Both 'if possible' and 'when possible' are commonly used in requests, agreements, and plans. However, they have distinct nuances and are not always interchangeable. Understanding these nuances can help improve communication and ensure that your intentions are clearly conveyed.

When to Use 'If Possible'

The phrase 'if possible' is used to acknowledge that a request might not be feasible in all circumstances. Using 'if possible' can be a tactful way to make a request, especially when the outcome is uncertain. Here are some scenarios where 'if possible' is appropriate:

When you are aware that the request might not be achievable under specific circumstances. When you are seeking permission or agreement that may depend on unforeseen issues. When you are aware that a person or entity may be unavailable or unable to meet the request at the moment.

Example:

I will discuss that matter if possible.

By using 'if possible,' you recognize that the matter might not be discussed, and this can soften the request.

When to Use 'When Possible'

'When possible' implies that the action is likely to be feasible but might be postponed due to other commitments or priorities. This phrase is more confident about the eventual possibility of the action. Here are some scenarios where 'when possible' is appropriate:

When you believe the action will be possible eventually but might be delayed due to other commitments. When you trust that the addressee is capable of fulfilling the request but may need to schedule it within their busy schedule. When the action is expected to happen in the future but is not certain until a later date.

Example:

Please find a gap in your schedule to meet up with me when possible.

By using 'when possible,' you are expressing confidence in the eventual possibility of the meeting but acknowledging that it might not be immediately possible.

Practical Examples

Here are some examples to illustrate the difference and usage of 'if possible' and 'when possible' in different contexts:

Example 1: 'If Possible'

A construction worker might say:

I want that ledge moved - if possible— to see if we can make another one above it.

In this example, the construction worker is asking for an attempt to move the ledge, but acknowledges that it might not be possible.

Example 2: 'If Possible'

A student might say:

If possible, I would like you there at the station at 2.15. If you really can’t make it, call me.

This shows a clear understanding that the request may not be possible, and alternative arrangements have been planned.

Example 3: 'If Possible'

In a confrontational context, a superior might say:

Johnson on duty this morning, I want you to MOVE NOT one inch from the sentry box— if possible!

This phrase shows a strong command, with an acknowledgment that the action might not be possible at the moment.

Example 4: 'When Possible'

A music teacher might say:

When possible, ladies I would like you to insert an appoggiatura— just before the High D— unless the next note is higher still.

This indicates that the action is expected to happen eventually but might be delayed due to other commitments.

Example 5: 'When Possible'

A chef might say:

I always get tomatoes in the summer when possible so we would not be having this dish in December.

This shows that the action is expected to be possible now but is not guaranteed until a future date.

Conclusion

Choosing the right phrase between 'if possible' and 'when possible' can significantly affect the tone and understanding of your communication. 'If possible' is used to acknowledge uncertainty, while 'when possible' expresses confidence in the eventual possibility of the action.

By mastering these nuances, you can enhance your communication skills and ensure that your intentions are clearly understood. Whether making requests, setting meetings, or providing instructions, the appropriate use of these phrases can greatly improve your professional and personal interactions.
