My lack of grammar education is showing me up again. In these examples, is 'was' correct, or should it be 'were'? I've had one reader tell me all my "if it was" should be "if it were" and I have no idea if she's right. This is written in past tense. If it [sex] was good, she’d keep seeing him. [Wondering who's knocking at the door] Oh god, if it was Sam… Neither of her friends knew a thing about fashion, or colour coordination, and if it wasn’t for her they’d be wandering around with washed-out skin. ...glaring at them [knickers/panties] as if it was their fault. “You wouldn’t have married if it wasn’t for the children?” What if it was life experience that made him so interesting? “It’s not love,” she said loudly. Everyone else she loved would leave her if it was. She tried to decide if it was blackcurrant or blackberry.
