### Re: Hardest alphabetical spellings

For French, I'm imagining something like keu -> queu -> queue, with the eu representing the same vowel as in bleu, the first u being mandatory after the q, and the final silent e as an FU. The English then probably couldn't resist the excessively French spelling and promptly forgot that they already...

### Re: a simple disproof of the abc conjecture

The quality is log(c)/log(rad(abc)) = log(9 n )/log(rad(9 2n -9 n )). The denominator might feel like it ought to approach log(rad(9 2n -9 n +¼)) = log(rad((9 n -½) 2 )) = log(rad(9 n -½)), but that's not really how the rad function works, and also, I think this isn't quite going where you wanted an...

### Re: a simple disproof of the abc conjecture

I mean, I guess a = 1, b = 9 n -1, and c = 9 n . Then rad(abc) = rad(9 n (9 n -1)) = 3 rad(9 n -1) ≥ 6. The last inequality holds because 9 n -1 is divisible by 8 = 2 3 . Of course, if n > 1, it must have other prime factors as well, since 9 n -1 is never a power of 2 unless n = 1, and since none of...

The hardest languages to write are sometimes considered to be those with logographic writing systems, especially Japanese. But among languages with alphabets, which ones have the most irregular or confusing spellings for native speakers? English is an obvious contender, but what else sits next to it?

Dictionaries are not rulebooks; they just document actual usage. But of course it is true that formal English is much more restrictive than informal English, and a construction that makes sense in conversation might be inappropriate or even incomprehensible in a formal context.
