In George Bernard Shaw’s Pygmalion (1913), which inspired the musical My Fair Lady, a fictional linguist describes a phonetic endemic: missed employment opportunities due to the connotations of a person’s accent. Addressing the “many thousands of men and women who have sloughed off their native dialects and acquired a new tongue”, the professor insists that “the thing has to be done scientifically, or the last state of the aspirant may be worse than the first”. Shaw’s wit shows through in the near homonym: aspirations of social mobility, in this period, often included pronunciationary emulation — the breathy aitch sounds of aspirated consonants.

Alfred Leach, who Steven Connor, in Beyond Words, calls one of the “doughiest defenders of the h”, believed that English’s aspirated aitch (or rather, haitch) signaled a direct inheritance from Classical antiquity. In the pronounced h of words like “herb” — notably lacking from American English — he heard the “spiritus asper” of Hellenism. Leach was writing in a period when linguists began reflecting on the shifting history of aspirates and the role they played in indicating status, class, and education. These traits continue into our present day. The historian of language Henry Hitchings, whose own name is uncannily reminiscent of Shaw’s Henry Higgins, argues that the pronunciation of this letter is “still a significant shibboleth”, and quotes Leach’s contemporary, Oxford scholar Henry Sweet, who called it “an almost infallible test of education and refinement”.

Why so much huffing about the letter H? Throughout the nineteenth century, this aspirated sound was on the rise. At the end of the previous century, Received Pronunciation (RP) became known as the accent of aristocracy, leading to aspirational elocution guides like Poor Letter H (1854). While words like “hotel” had once been pronounced in the French style (oh-tell), English speakers had begun to exhale audibly, as if yawning at the continued Norman influence on British tongues. Leach led the charge against “English Grammarians” who “conspired to withhold from us the means of propitiating this demon Aspirate”. In The Letter H, he ridicules those he calls “H-droppers”, speakers whose phonetic errors seem to snowball: “lost H’s have a knack of turning up in wrong places, when they return at all”. Leach is prone to hyperbole — “the early aspirative labours of a converted H-dropper give birth to monstrosities” — and sneers at Cockney speech: “Horkney hoysters, ‘amshire ‘am, and ‘am and heggs”.

To tell his story correctly, the linguist lapses orthographic, going back to the H’s origin in Egyptian and Phoenician characters. Working his way up to the present, Leach proclaims that “the modern English H is an important embellishment, and adds immensely to the strength and pleasing effect of speech”. At times, in this book, the H seems semi-animate. It’s “an earnest letter” and brings excitement into the language: “Ho! Ha! Hollo! Hurrah! Hang it!”. Leach ends his surprisingly captivating linguistic treatise by waxing maudlin. “Any letter doomed to die out of a word or a language, generally attempts to depart gracefully by first acquiring the nature of an aspirate-consonant, and then turns into a perfect H; under this form it relies upon h-dropping mortals to give it quiet burial, and unobtrusively confide it to Oblivion.” Markedly grumpy, Leach may have found himself hopeful had he heard the aspirated h humming along in our language today.
