n
Talk that is boring, meaningless, or nonsense.
interj
Used to represent boring or meaningless speech, or to express a feeling of indifference.
Etymology
The word 'blah' is a relatively modern English formation, first recorded in the early 20th century. It is an onomatopoeic or echoic creation, directly imitating the sound of someone speaking in a dull, uninterested, or monotonous manner. There is no deeper etymological lineage to Proto-Indo-European roots; its logic is purely phonetic, capturing the essence of meaningless chatter through its flat, unvaried sound. Its adoption and expansion into a noun and interjection demonstrate language's capacity to create expressive terms from sensory experience.
Analysis
This is a simplex word of imitative origin, created to mimic the sound of dull, repetitive speech. It functions as an ideophone.
