Common misconceptions
❝ Every modal must change in reported speech. ❞
Not every modal changes. Could, might, should, and would normally stay the same, and an unchanged modal is also possible when the meaning is still true now.
❝ Reported must always stays must. ❞
For reported obligation, English often uses had to. Keep must only when that unchanged meaning is the better fit.
Skills in this rule (6)
CHANGE_CAN_TO_COULDw5Change can to could in reported statements
When you report a past statement with can, use could in the reported clause. Keep the rest of the meaning the same.
CHANGE_MAY_TO_MIGHTw5Change may to might in reported statements
When the original statement uses may and the reporting is in the past, report it with might. This keeps the idea of possibility or permission.
REPORT_MUST_AND_HAVE_TOw5Report must and have to with the right form
In reported statements, must often becomes had to for obligation. Use had to when you report a duty or necessity from the original statement.
KEEP_COULD_MIGHT_SHOULD_WOULDw4Keep could, might, should, and would unchanged
Some modals do not change in reported statements. If the direct sentence already has could, might, should, or would, keep that modal.
CHOOSE_NO_CHANGE_WHEN_TRUE_NOWw4Keep the modal when the meaning is still true now
Sometimes a modal does not change because the speaker reports something still true, still possible, or still allowed now. Choose the unchanged form when the present reality matters more than backshift.
NOTICE_REPORTED_SPEECH_CUESw3Recognize cues that signal reported speech
Words like said, told me, explained, and asked introduce someone else's words. These cues help you expect reporting changes in the next clause.
