Haha ਹ

Haha is the fifth letter of the Gurmukhi painti and the second of the two consonants placed ahead of the five ordered series. Written plainly it is an h. What makes it one of the most interesting letters in the script is that in Punjabi it is also a carrier of tone. Punjabi is unusual among the Indo-Aryan languages in having developed lexical tone, and the letters implicated in that development are Haha and the four voiced aspirates of the consonant series. In a large class of words the h is weakened or lost in speech and the pitch of the neighbouring vowel changes instead, so that the letter on the page records a consonant while the mouth produces a tone. Haha is also one of only three letters in the script with a reduced subjoined form, written beneath the consonant it follows rather than beside it.

The older orthography of the Guru Granth Sahib uses that subjoined form freely, where modern Punjabi print generally writes the full letter, so the shape is one of the visible differences between a scriptural page and an ordinary one. Tone is the feature that most surprises readers who come to Punjabi from the other Indo-Aryan languages, none of which has it in the same way, and Haha is one of the two written sources of it. The other is the set of voiced aspirates. Between them, those letters account for the whole of the tonal system without any mark of their own, which is an unusually economical piece of orthographic engineering, though an accidental one.

The subjoined Haha is a small mark, and its treatment is one of the clearest cases in Gurmukhi of the scripture holding a form that ordinary usage has let go. In manuscript copies of the Guru Granth Sahib it appears constantly, tucked beneath the letter it belongs to and leaving the headline unbroken. Modern printed Punjabi tends to spell the same words with a full Haha in sequence, which is easier to set and easier to read at small sizes but produces a visibly different page.

Because Sikh practice treats the volume as a living Guru and does not permit its wording to be modernised, printed editions of the scripture reproduce the subjoined form, and a Gurmukhi typeface intended for scriptural work has to carry it. The letter also poses a question for anyone reading the scripture aloud. Where Haha marks tone rather than a pronounced h, a reciter must decide what the text is asking for, and the answer is not the same for a scholar reading historically as for a congregation reciting in a living register. Sikh institutions teach recitation as a disciplined skill for that reason, and the handling of Haha is among the things taught rather than assumed. The subjoined form also matters for digital text. It is encoded as a distinct sequence rather than as a separate character, so a font that does not implement the joining behaviour will render the scripture wrongly while leaving ordinary Punjabi looking correct, a failure that is easy to miss in testing.
