Expert writing Tips
Best practice
Always use the correct preposition, which is "by", instead of "from" when you mean that something is distinguished or identified by a particular characteristic. For instance, use "The study is characterised by its thorough methodology" instead of "characterised from".
Common error
Avoid using "from" after "characterised". The correct preposition to use is "by". Using "from" suggests that the characteristics originate from something, rather than define it. So, instead of saying, "The landscape is characterised from its rolling hills", say "The landscape is characterised by its rolling hills".
