Sluices on indefinites or disjunctions may seem to require wide scope for those – but then again, there is a confound…
The following examples may seem slightly odd:
- We have to find someone who knows Arabic but we haven't been told who yet.
- Somebody always complains about the sound quality. You'll know who soon enough.
- You may have a beer or a glass of wine with the evening meal. I don't remember which though.
How is that?
Now the following example may seem to break ranks with (1)–(3) in allowing two readings:
- Everybody ordered a starter, but the waitress forgot what.
Do you agree? How could the "new" reading be characterized? (Keyword: 'pair-list')
