Etymology: Emerging in English during the early 17th century, this adjective reflects a fusion of temperamental qualities. It likely derives from the noun "pet," which in older English usage could mean a favored child or a spoiled person, combined with the suffix "-ish," which forms adjectives indicating a characteristic or tendency. The root "pet" itself traces back to an uncertain origin, but by the time this adjective appeared, "pet" had taken on connotations of fussiness or capriciousness. The word captures a mood marked by irritability and peevishness, suggesting someone who is easily upset or prone to sulking. This nuance connects it to the older sense of "pet" as someone indulged or pampered, who might then become quarrelsome or fretful when things do not go their way. The suffix "-ish" transforms this into a descriptive term, pointing to a disposition rather than a concrete identity. Over time, the adjective has come to emphasize not just spoiled temper but a general touchiness or testiness. It aligns with a cluster of words like "pettishness" and "petulant," all evoking a fretful or irritable character. While "pettish" itself is somewhat archaic in modern usage, it retains a poetic flavor, often employed to describe delicate moods or whimsical irritations reminiscent of the fussiness once associated with a "pet" in the domestic sense.
