masculine nominative singular, with -ti enclitic copula
Analysis. appaṭi-puggala + iti: a-ppaṭi-puggala, "not (having) a counter-person", + the enclitic copula iti "it is". The prefix a- negates ppaṭi-puggala (where ppaṭi is the prefix paṭi- "back, counter to" + puggala "person, individual"), yielding "one to whom no peer stands opposite".
Etymology. Compound of a- (negation) + paṭi- (back, against, counter to; from PIE *poti-, appearing in Greek pros, Latin contra) + puggala (person; from Sanskrit puruṣa, related to Greek pyr- and Latin par-, both meaning peer or equal). The prefix paṭi- carries the spatial image of standing opposite or facing back; negated, it means "without a counterpart facing back", i.e., matchless.
