Expert writing Tips

Best practice

When describing someone's feelings or apologies, use "not sincere" to express that they are disingenuous or lack true emotion.

Common error

Avoid using "not sincere" when you mean someone lacks skill or expertise. Sincerity refers to genuineness of feeling, not competence. For example, instead of saying "His attempt at painting was not sincere", say "His attempt at painting was unskilled" or "amateurish".
