The same words mean different stitches. A US double crochet and a UK double crochet are not the same thing, and both shorten to “dc” — so a pattern can read perfectly sensibly and produce entirely the wrong fabric. If a pattern does not say which it uses, look for single crochet: it exists only in US terms.

| yo | Yarn Over | yoh | Yarn Over Hook |
The quick version: UK names are one step taller than US ones all the way up the ladder — US single is UK double, US double is UK treble. The hook and the yarn never change; only the word does. US names count the yarn overs you make before the stitch, UK names count the loops left on the hook after the first pull-up, which is why they never lined up.
