A circumfix (abbr: CIRC)[1] (also parafix,[2]confix, or ambifix) is an affix which has two parts, one placed at the start of a word, and the other at the end. Circumfixes contrast with prefixes, attached to the beginnings of words; suffixes, attached at the end; and infixes, inserted in the middle. Circumfixes are common in Malay[3] and Georgian.[4]
Its related operation is called circumfixation (or parafixation, confixation, ambifixation).
