Nuance or False?
When Mrs Parsons' sink was broken she asked Winston to fix it.
Mrs Parsons said that to Winston
'Of course if Tom was home he'd put it right in a moment,' she said. 'He loves anything like that. He's ever so good with his hands, Tom is.' *
But her husband, Tom, was at work so he could not have fixed it. Mrs Parson was talking conditionally about 'unreal' circumstances.
Could Mrs Parson have said that
'Of course if Tom were here he'd put it right in a moment.'
in that case if Tom had been died, or they have been divorced?
I mean, is there any differece between 'was' and 'were' in a situation, like this?
Does 'were' refer to a more unlikely possibility, or I am absolutely wrong?
* citation from '1984' by George OrwellOr another example
'If I were home I could check it it for you.'
'If I was home I would check it for you.'
Can the second one mean that 'as soon I get back to home I will check it' contrasted with the first one meaning 'I am not at home so I cannot help'?
