Exhaustive Absence with 无A无B in Chinese
无A无B
无A无B is a compact four-part pattern combining two parallel absent properties or limits. Some forms are productive descriptions, while others, such as 无法无天, are lexicalized idioms. Both 无 markers and both balanced slots are required; aspect, classifiers, and unrelated clause material cannot interrupt the formula.

无A无B is a compact four-part pattern combining two parallel absent properties or limits. Some forms are productive descriptions, while others, such as 无法无天, are lexicalized idioms. Both 无 markers and both balanced slots are required; aspect, classifiers, and unrelated clause material cannot interrupt the formula. Keep the model 无 + A + 无 + B visible while you compare each sentence.
她无时无刻不在想念家人。
She misses her family every moment.
Choose the right context
Use established 无A无B forms to deny two parallel properties. Use 无时无刻 with 不 for an emphatic always reading. Keep lexicalized idioms such as 无法无天 intact.
这个孩子越来越无法无天。
This child is becoming increasingly unruly.
Respect the boundary
Do not omit the second 无. Do not insert aspect marking inside the four-part formula. Do not freely invent A and B combinations without an interpretable parallel relation.
她无时无刻不在家人想念。
(She misses her family every moment.)
Repair the pattern
Object precedes rather than follows the verb inside the fixed frame: Inside the 无时无刻不在 frame, object 家人 must follow transitive verb 想念; it cannot intervene before the verb. Aspect marker splits a lexicalized formula: 无法无天 is an indivisible idiom and cannot contain aspect 了.
她无时无刻不在想念家人。
Use the repaired structure without changing the intended meaning.

08 / QUESTIONS
Exhaustive Absence with 无A无B Questions
Why does 无时无刻 often take 不?
The outer negative combines with the exhaustive no-time expression to yield an emphatic always reading.
Is every 无A无B combination productive?
No. Many common forms are conventional or lexicalized and should be learned as units.
