The diction used in the line "I shall booze and zoom myself home" from Onu's "A Government Driver on His Retirement" is onomatopoeic. Onomatopoeia refers to the use of words that phonetically imitate, resemble, or suggest the sounds they describe.

The word "zoom" directly imitates the sound of rapid movement - the whirring, rushing sound of a vehicle speeding along a road. In the context of a retiring government driver, "zoom" evokes the noise and sensation of driving at high speed. "Booze," while primarily meaning to drink alcohol, also carries a buzzing, humming quality in its pronunciation that contributes to the onomatopoeic texture of the line. Together, "booze" and "zoom" create a sound-rich, energetic effect that conveys the driver's exuberant plans for his retirement.

The diction is not veiled (indirect or hidden in meaning) - the speaker's intention to drink and drive fast is stated plainly. It is not complex - the words are simple and vivid. And it is not formalised - the register is casual and colloquial, far from the formal language of official communication.
