They have done before, too.
Yes, I know. Many people do use ‘celibate‘ to mean ‘not having sex‘. But, that becomes very convoluted when you apply it to married folks because the true definition of ‘celibate’ is not being in a relationship. That is how ‘celibate’ came to have this secondary meaning, though it is no longer the case, i.e., IF you are not in a relationship then you are not having sex!
The correct word is ‘continence‘ or ‘abstinence’.
Yes, the improper use of this word bugs I. But, I am a pedant as to the correct usage of the Queen’s beautiful English.
