Why is it that people persevere with out-of-date language that they’d never utter in a face-to-face conversation? Would you say: “My family consists of five persons, currently domiciled in a brick residence” or “There are five people in my family, and we live in a brick house”?
Many people think that elaborate sentences and multi-syllabic words makes them better writers. They don’t.
How many times have you said: “do not hesitate” or “at your convenience” in speech? I bet never. These once-popular phrases are no longer plain English, because they are not what you would say in face-to-face discussions or in telephone conversations. They are not your own words.
When you write this way, it affects the reader’s perception of you. Dated language gives the impression that you are a bit out of date yourself.
