I'm beginning to learn the use texmaker. I have enabled the texmaker dictionary. I wonder whether there is any option by which I can enable it to prompt or suggest words while writing.
You can use a very similar yet more powerful latex editor, texstudio, to achieve this (texstudio and texmaker develops from the same software yet follows different philosophy and routes, texstudio being more configurable, texmaker being more compact). For details, refer to my answer in Use dictionary for completion
