I'm writing in present tense in my WIP and have been getting a bit confused over which tense to use. Should it be: As if he was a ghost. Or should it be: As if he were a ghost. And what about "could" and "would" etc? Should it be: As though he had all the time in the world. Or: As though he has all the time in the world. Personally I've always gone for "As though he had" and "As if he were" - but my friend keeps changing it back to "As though he has" and "As if he was". I thought you were meant to convert the verb, such as "If I were you..."? Normally it would be "I was" but because of the conditional form, it turns into "were". And I've also never been sure about the grammatical rules when it comes to conditionals. When do you say "If you can" and "if you will" versus "if you could" and "if you would"?
