@JTT,
I can't comment on why someone else might feel comfortable saying were in those instances but I have a question about an ancillary issue- and I think you might know the answer.
My understanding is that one uses 'were' as the subjunctive- something that might happen- as in 'If I WERE to go to the party, I would wear blah, blah, blah...or 'If I WERE going to the party....etc.
So this is what I've always said (and written). But I've noticed in more and more publications (mostly newspapers and magazines) that people are using 'was' instead of 'were'.
I've read sentences such as, 'If I was going to the party...'
That just sounds wrong to me, but I figure these editors must know what they're doing.
Can you use 'were' and 'was' interchangeably? Are they equally grammatically correct or is one more favorably looked upon than the other?
And if they are interchangeable- is this a fairly recent grammatical development or change?
