# Preventing line breaks in superscript

Word is imposing a line break and causing a superscript (which is part of a unit) to be split across 2 lines; e.g.

``````...foo bar 30 ms ⁻
² foo bar...
``````

which obviously looks a little wrong! I've tried selecting / deselecting the orphan controls / keep with next / keep lines together in the paragraph options box. Is the only way round it to manually put in a Ctrl + Enter or is there a more proper way to solve the issue?

• @martineau Apologies. What don't you understand? – ChrisW Nov 21 '12 at 19:26
• @martinau sorry; I sometimes forget other peoples' knowledge on science notation isn't post-high school! `ms^-2` is equivalent to 'metres per second squared' and is the unit of acceleration. A superscript `-` is the standard way to denote 'per' (hence the mathematical way of writing 'metres per second' - the unit of speed - is `ms^-1`, rather than `m/s`). I'm not doing anything rather than writing a normal piece of text in a normal paragraph. There shouldn't be a line break inbetween the superscript `-` and the superscript `2`-all 5 characters of the unit (`ms -2`) should be on the same line – ChrisW Nov 21 '12 at 19:36
• @martineau no - the superscript `-` is as important (`ms^2` is a different unit to `ms^-2`) :) I type in `foo bar 30 ms-2` near the end of a line (when the paragraph is justified) - this makes the `2` go onto the next line; I then make the `-2` superscript and the result is that the `2` is still orphaned on the next line. Perhaps Word thinks that my `-` means I allow a line-break because it's a hyphen? – ChrisW Nov 21 '12 at 19:54
• @martineau - I've sorted the problem :) see my self-answer – ChrisW Nov 21 '12 at 19:59

• Regarding the third option, you simply write `"ms"^-2` (literally, with the quotes) in the formula box. The quotes will make `ms` non-italic. Also, to change the font from Cambria Math to the body matter font of the rest of the document, simply select `ms` and change the font! – Andreas Rejbrand Nov 22 '12 at 12:44
