If you look carefully at this clip from the Daily Telegraph web edition, under the picture it says 'Click to embiggen'.
I'm curious about this choice of word – is it possibly a little sardonic, given the topic?
It's not one I've seen before, so I looked it up. Apparently, it started in a 1996 episode of the Simpsons: read about it on the Future Journalism Project's blog.
There's no doubt we need a single word for 'make bigger'. Somehow 'enlarge' always sounds more written than spoken.
In our studio we used to use the verbs 'to bigger' and 'to smaller' when discussing type size, as in 'Can you try biggering the headline there?'.
