Irreversible word pairs are a pair (or group) of words that always appear in the same order. ⁣
⁣
They are a bit like collocations in that they are often seen together, and they often come up in IELTS.⁣
⁣
E.g.: first and foremost/trial and error/facts and figures⁣
⁣
Here are some common word pairs. Can you finish each pair?⁣
