How One‑Word Substitutions Make Your Writing Professional
Using precise one‑word substitutes demonstrates a mature vocabulary and saves space in your writing. Board examiners look for this skill in essays, letters, and reports. Instead of writing "a person who cannot read or write," simply use "illiterate." Instead of "a speech delivered without preparation," say "extempore." Start integrating these words into your answers gradually. Pick ten words each week from this list, learn their meanings, and challenge yourself to use them in your classroom writing. Your expression will become noticeably sharper and more professional.
