• baddha-vairau — whose enmity is fixed
  Compound dual: baddha (bound) + vaira (enmity). The vaira is not fresh anger but tied-up, knotted hatred. Gauḍīyas note that vaira can in some cases lead to liberation (śiśupāla, kaṁsa) — but only when the vaira is directed toward the Lord. Vaira between embodied egos only binds further.
• anusmarantau — continuously remembering
  Present participle dual of anu + √smṛ. Anusmaraṇa is the technical term for sustained memory — the same word-field that names bhakti's smaraṇa. Here it is bent the wrong way: they continuously remember each other's misdeeds instead of the Lord's pastimes. The verb is a dark double of bhakti.
• duruktam duṣkṛtāni — harsh words and misdeeds
  Pair: dur (bad) + ukta (spoken) and dur (bad) + kṛta (done). The ledger of grievance has two columns — what was said and what was done. The verse names both as the content of misdirected anusmaraṇa.
• artha-vat — sensible, reasonable
  Compound: artha (meaning, sense) + vat (possessing). Balarāma's speech was artha-vat — full of sense — yet rejected. The Bhāgavatam is precise: rejection of the Lord's word is not always a rejection of logic; sometimes the heart has already chosen and the argument is irrelevant.

Even a logical word from Bhagavān's elder brother cannot move two men whose hearts have been holding a grudge for thirteen years. The duel continues because anusmaraṇa — continuous remembering — has gone the wrong way: instead of remembering Kṛṣṇa, both warriors have spent years remembering each other's insults. The Bhāgavatam quietly shows what happens when smaraṇa is misdirected; it becomes vaira-baddha, bondage by enmity.
