I enjoyed your series, especially last Thursday's program on the letter
'X'. Bearing in mind that we speak a language with forty-four phonemes
(twenty-four consonants, twelve vowels and eight dipthongs) which we
write with the twenty-six letter version of the Roman alphabet: we waste
several letters. Mostly 'X' does the work of 'K' and 'S'. It could be
used for a single sound.
