Are the sentences grammatically correct?

He hadn't been cleaning Suzi's room while she was ill.

He wasn't cleaning Suzi's room while she was ill.

PS: I think I should have added a request for context. Could you come up with contexts in which they can be used?

  • Is Suzi "her"? It would be clearer if you put Suzi first and the pronoun second.

  • I'm asking about "her". Is that Suzi? Does this have the same meaning: "He hadn't been cleaning Suzi's room while she was ill"?

    It isn't a minor point; 'her' could be someone whose room Suzi normally cleaned, and 'he' hadn't been standing in for Suzi while she was unable to do it. Nov 13, 2022 at 9:06

    @user1425 Because having unnatural structure in sentences makes it difficult to assess the naturalness of the whole sentence, even parts you're not asking about.

As I know they are because with when while (that already emphasize simultaneous reference) you can ignore sequence of tenses

  • Your sentence isn't at all clear, Petro. Nov 13, 2022 at 9:07
