pan-


a combining form meaning “all,” occurring originally in loanwords from Greek (panacea; panoply), but now used freely as a general formative (panleukopenia; panorama; pantelegraph; pantheism; pantonality), and especially in terms, formed at will, implying the union of all branches of a group (Pan-Christian; Panhellenic; Pan-Slavism). The hyphen and the second capital tend with longer use to be lost, unless they are retained in order to set off clearly the component parts.
Also pant-, panto-.
