- Believe in
- Have faith in
- Have confidence in
- Accept as true
- Trust in
- Be certain of
- Be sure of
- Be confident of
- Be convinced of
- Have no doubt about
Using these alternatives can make the text more interesting to read and help the writer express their thoughts more precisely. It's important to choose the synonym that best fits the context and conveys the intended meaning.
