Brit.

/ˌpɑliˈsɪmətri/

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: poly- comb. form, symmetry n.

Etymology: < poly- comb. form + symmetry n., after German Polysymmetrie ( J. Sachs Lehrb. der Bot. (ed. 3, 1873) III. iii. 90, in sense 1; P. Groth Einleitung in die chem. Krystallogr. (1904) 4, in sense 2). With sense 1 compare monosymmetry n.
