I know you’ve got a spellchecker!
Consider the different meanings of these words:
Their / There
Where / Were / Wear
Hare / Hair
Except / Accept
Effect / Affect
It’s / Its
The computer can’t interpret what you want to say. It doesn’t know whether you wondered what you might where after you’d washed your hare. It can only tell you when you misspell a word, commit a grammatical error or fragment a sentence. It can be a useful aid but you can’t rely on it to correct your work for you.
What I can do
I can check for misspellings and grammar errors and keep consistency in documents. I can also highlight text that doesn’t sound quite right or is difficult to understand, which is essential if your document is to be read and understood by your clients and their customers. All this goes to enhance your work and create that professional image you’re looking for.
And I would know that you had washed your hair before wondering what to wear unless, of course, your document was discussing the cleanliness of long-eared mammals!
