For a few years I've noticed that a lot of people refer to any school holiday as half term (except the summer holiday which is pretty much always called the summer holiday).
Now, when I was at school (ok it was a while ago), half terms were the week you would get off half way through the term, e.g. in October, February and May. The longer holidays were the Christmas and Easter holidays, NOT half term.
But now they all seem to he know as 'half term'. I've noticed it a lot on here as well as real life. I am probably massively unreasonable to get annoyed by it but every time I hear it it makes me twitch. How can it be half term at the end of a term?
