(k+1)th, (k+1)st, k-th+1, or k+1? (Inspired by a question already at english.SE) This is more of a terminological question than a purely mathematical one, but can possibly be justified mathematically or simply by just what common practice it. The question is: When pronouncing ordinals that involve variables, how does one deal with 'one', is it pronounced 'one-th' or 'first'? For example, how do you pronounce the ordinal corresponding to $k+1$? There is no such term in mathematics 'infinityeth' (one uses $\omega$, with no affix), but if there were, the successor would be pronounced 'infinity plus oneth'. Which is also 'not a word'. So then how does one pronounce '$\omega + 1$' which is an ordinal? I think it is simply 'omega plus one' (no suffix, and not 'omega plus oneth' nor 'omega plus first'. So how ist pronounced, the ordinal corresponding to $k+1$? * 'kay plus oneth' * 'kay plus first' * 'kay-th plus one' * 'kay plus one' or something else?
