1st person singular present indicative of mettacittohaṁ, a contraction/fusion form from mettacittena ahaṁ asmi (literally "with a kindly heart I am")
Analysis. metta-citta-ha-mi: metta ('loving-kindness, friendliness') + citta ('heart, mind') + ha (contraction of ahaṁ 'I') + mi (1st sg. pres. ending). The surface form shows Pali's tendency to absorb pronouns and merge inflected phrases into single orthographic units in verse and formulaic speech.
Etymology. metta (from √mi- 'to smile, be friendly'; related to Sanskrit mitra 'friend') + citta (from √cit- 'to perceive, think'; cognate with English cognition, Latin cogitare). The compound expresses the doctrinal virtue of mettā (one of the four brahmaviharas or divine abodes in Buddhist practice).
