PIE word
*dwóh₁
Borrowed from Latin duplex (“double, two-fold”), from duo (“two”) + plico (“fold together”); compare the roots of διπλόος (diplóos, “double”); compare also πλέκω (plékō, “twist, braid”). By surface analysis, duo- + -plex.
Meanings
(not-comparable) Double; made up of two parts. ▸ Having two floors.
(not-comparable) Double; made up of two parts. ▸ Having two units, divisions, suites, or apartments.
(not-comparable) Double; made up of two parts. ▸ Of stainless steel: having a structure containing austenite and ferrite in roughly equal proportions.
Duplex stainless steels have been classified according to the first period (1930–1960) and second period (1960–1990). The designations for these duplex alloys in the United States have been primarily according to Unified Numbering System (UNS) numbers in the S3xxx.x series. 2010, Harold M. Cobb, The History of Stainless Steel, Materials Park, O.H.: ASM International, →ISBN, page 189:
(not-comparable) Bidirectional (in two directions).

Meanings
(Australia, Canada, US) A house made up of two dwelling units.
The house had been renovated into a duplex and he’d put in a phone line. 2020, Akwaeke Emezi, The Death of Vivek Oji, Faber & Faber Ltd, page 53:

A cancellation combining a numerical cancellation with a second mark showing time, date, and place of posting.
A throwing motion where two balls are thrown with one hand at the same time.
A double-stranded polynucleotide.
A system of multiple thrust faults bounded above and below by a roof thrust and floor thrust.
It has been noted, using a combination of surface geologic and seismic reflection data, that a duplex, although formed in response to movement of a thrust sheet, frequently arches the thrust sheet as the duplex is built by duplication of rocks beneath it […] 1995, Robert D. Hatcher, Structural Geology: Principles, Concepts, and Problems, page 211:
In contrast, the folds in the overlying lithotectonic unit 4 are larger and are cut by a series of faults in a duplex. 1993, David J. Lidke, Jack Burton Epstein, Chester A. Wallace, U.S. Geological Survey Bulletin, page 16:
