S words worth using in your writing
Sardonic describes dry, mocking humor that is slightly cruel — more precise than "sarcastic". Scrupulous means having a careful regard for doing what is right — stronger than "careful" or "thorough". Stoic describes someone who endures hardship without complaint — from the ancient Greek school of philosophy. Sublime means of such excellence that it inspires awe — stronger than "beautiful" or "great". Succinct means expressing something clearly in few words — more precise than "short" or "brief". Sycophant names a person who flatters powerful people for personal gain — irreplaceable for that specific combination.
