How do I announce a death or funeral without finding the perfect words?

You do not need polished language. People usually need the name, what happened in the simplest appropriate terms, the service details if known, and any practical request from the family.

Simple death announcement

With great sadness, we want to let you know that [Name] died on [day/date]. We are still taking things in and are grateful for your kindness. We will share funeral or memorial details when they are confirmed.

Death and service details

If the family needs quiet

Thank you for your care for our family. We are not able to answer many calls right now, but messages are welcome and we will read them when we can. We will share practical information here as it is confirmed.

If people are asking how to help

Thank you for asking how you can help. The most useful things right now are [meals / transport / help with children / reception food / practical errands]. [Name] is coordinating this for us at [contact details].

Before you post publicly

Make sure close family and important friends have been told personally where possible.
Do not publish a home address, access code or other information that does not need to be public.
If service arrangements may change, say that details will be confirmed rather than guessing.
If there are difficult circumstances around the death, you are allowed to keep the public wording brief.
