ind.
Etymology. The word khalu is an emphatic particle of Sanskrit origin (khalu), functioning as an indeclinable marker of assertion or emphasis. It may derive from a root sense of 'being firm' or 'holding', though the etymology within Pali itself is opaque. The particle serves to strengthen the force of a statement, marking it as definite, reported, or noteworthy—a pragmatic function rather than one whose origin is recoverable from morphology.
