I like this entry in Neil MacAlpine's "Pronouncing Gaelic Dictionary", first published in 1832 -
"H, h, this letter is not acknowledged in our Alphabet; but to keep the Gaelic in character with us, who are the BRAVEST and most singular people in the WHOLE WORLD, (as the SCOTS TIMES says,) it is used, not only in every word, but almost in every syllable expressed or understood."

Another entry begins -
"TAPADH ... heroic feat, achievement; thanks, success; tapadh leat thank you, Sir, or Madam - literally may you be a hero or heroine, (the thing uppermost in Donald's noddle) ..."
