In English, many people like to use phrasal verbs when talking and writing. For many, it is simply easier and more natural to utilize these words. Some examples might be to look up, ask for, or put off. Once again, it’s very normal for people to use these phrasal verbs. However, in a formal setting like an email or a meeting with superiors, it may be better to use formal language. This sets the tone and makes you seem more professional even though the meaning of the words are exactly the same.
