It's probably a more useful word.

Today in French we were going over new vocabulary in the piece we'd just read, and the teacher was describing a word as "one who has to do with children, and interests themselves in them" and then when she said "yes, nursery nurse" to someone she queried my look of complete bafflement, which was because I'd slightly misunderstood something she'd said and completely thought she was describing a paedophile.

In fairness to me, we were reading about abused children, but even so I think perhaps that was not the impression I wanted to create. Although maybe now she'll remember my name after three weeks of calling me Carla.
