Grammatical Analysis
Hetupaccaya: [m.] Root condition. Formed by hetu (root, primary cause) + paccaya (condition, relating factor).
Orthodox Definition
Hetu-paccaya is the very first of the 24 Conditions enumerated in the Paṭṭhāna. It describes the specific causal relationship where a fundamental root stabilizes and nourishes the mental and physical phenomena that arise alongside it.
In Abhidhamma, there are exactly six roots: the three unwholesome roots — greed (lobha), hatred (dosa), delusion (moha) — and their three opposites, the wholesome roots — non-greed (alobha), non-hatred (adosa), non-delusion (amoha).
The classic commentarial simile for Hetu-paccaya is a tree root. Just as the roots of a tree firmly anchor it to the earth and draw up nutrients allowing the trunk and branches to grow and flourish, the six mental roots anchor the associated consciousness (citta) and mental factors (cetasikas) firmly into their object, giving them stability and defining their ethical quality.

Explanation of the Paṭṭhāna Method (from Abhidhammatthasaṅgaha)hetu ca so paccayo cāti hetupaccayo.
It is a cause (hetu) and it is a condition (paccayo); thus, hetupaccayo (root-condition).hetu hutvā paccayo, hetubhāvena paccayoti vuttaṃ hoti.
It means that it is a condition by being a root, a condition by way of its root-nature.mūlaṭṭhena hetu, upakāraṭṭhena paccayoti saṅkhepato mūlaṭṭhena upakārako dhammo hetupaccayo.
A cause in the sense of a root, a condition in the sense of a helper; in brief, a phenomenon that helps in the sense of a root is a hetupaccayo.so pana pavatte cittasamuṭṭhānānaṃ, paṭisandhiyaṃ kammasamuṭṭhānānañca rūpānaṃ ubhayattha sampayuttānaṃ nāmadhammānañca rukkhassa mūlāni viya suppatiṭṭhitabhāvasādhanasaṅkhātamūlaṭṭhena upakārakā cha dhammāti daṭṭhabbaṃ.
This should be understood as the six phenomena (greed, hatred, delusion, non-greed, non-hatred, non-delusion) that act as helpers by way of their root-nature, which serves to establish firmly, like the roots of a tree, the mind-born rūpas in the course of existence, the kamma-born rūpas at the time of rebirth, and the conascent nāma-dhammas in both instances.
