I think good grammar is important and attractive! As a VA, it is part of my job to notice grammar, spelling and the proper use of words. Common mistakes can do serious damage to an otherwise stellar reputation. Think about the image you project and proofread, do some research, look it up…or ask me!
And let me say that this one is a major pet peeve for me. So many people do not use these words correctly.
Than Then
Which is correct?
Chocolate ice cream is better than vanilla.
Chocolate ice cream is better then vanilla.
The correct choice is the first sentence using than.
Than is a subordinating conjunction. It is used in comparisons, as in the example sentence above in which two flavours of ice cream are being compared.
Then is considered a conjunctive adverb. It is used in reference to time, indicating that one action follows another.
We spent the morning sightseeing; then we stopped for lunch at a local restaurant.
Then and than are often pronounced as if they were the same word, which may explain why they are frequently confused in writing.
