A eulogy or funeral speech can be a difficult undertaking. If you were not close to the deceased you may not know much about them. If you were very close, you may have too much you want to say to fit into the eulogy. Most people have no idea where to begin.
The best place to start is with eulogy examples. Read several eulogies online to see what you should and should not include in your funeral speech. It does not have to be elaborate, but should show respect and love for the deceased. If you are still unsure of where to begin you can easily find eulogy templates online to help you get started.
A eulogy should introduce the lost loved one, giving their full name, spouse name whether alive or dead, and survivors such as children and grandchildren. It should also give a brief description of the character of the lost, and perhaps include a touching story about their lives.
In general a eulogy is not long. It is an opening to the funeral services. Typically others in attendance will come forward with their own personal thoughts, feelings and stories of the deceased. The eulogy is not meant to stand alone. It is but an introduction to start things off.
When you look at eulogy examples you will also notice that most of them are fairly simple. They do not have to be a beautifully written piece of prose. Keep the format and vocabulary simple. You do not know who might be in your audience, and you want it to be understood and appreciated by all.
When in doubt, refer back to eulogy examples you have found online, or look for additional samples. You will find the inspiration and guidance you are looking for. It is difficult to write a eulogy, especially for a dear loved one, but with the tools available the semantics should be much easier.
