In Greek:
1/ «Σύζυγος» ['siziɣos] (masc & fem) --> spouse, husband (masc), wife (fem) < Classical noun «σύζυγος» 'sŭzugŏs (masc & fem) --> yoke-fellow, comrade, spouse united by marriage; compound, prefix and preposition «σὺν» sŭn --> beside, with, together with (PIE *sem-, together) + masc. noun «ζυγός» zu'gŏs --> yoke (PIE *yewg-, to yoke, harness, join). The wife refers to her husband as «o σύζυγός μου» [o 'sizi,ɣos mu] (note that the possessive genitive pronoun «μου» is enclitic) --> the (masc. definite art.) husband of mine, while the husband refers to his wife as «η σύζυγός μου» [i 'sizi,ɣos mu] --> the (fem. definite art.) wife of mine.
2a/ «Άνδρας»* ['anðras] (masc.) --> man < Classical noun «ἀνήρ» anḗr (masc.) --> man (PIE *h₂nḗr, man). The wife refers colloquially to her husband as «ο άνδρας μου» [o 'anðras mu] --> the man of mine.
2b/ «Γυναίκα»* [ʝi'neka] (fem.) --> woman < Classical noun «γυνὴ» gunḕ (fem.) --> woman (PIE *gʷḗn, woman). The husband refers colloquially to his wife as «η γυναίκα μου» [i ʝi'neka mu] --> the woman of mine.
* Modern Greek nouns (especially those masculine and feminine ones belonged to the ancient third declension) form their nominative by taking the ancient accusative, e.g:
-Ancient Greek «ἀνήρ» anḗr (sing. nom. masc.) --> man, gives «ἄνδρα» 'andră in the accusative, from which the Modern Greek «άνδρας» ['anðras] (sing. nom. masc.) derives.
-Ancient Greek «γυνὴ» gunḕ (sing. nom. fem.) --> woman, forms «γυναίκα» gunǽkă in the accusative, from which the Modern Greek «γυναίκα» [ʝi'neka] (sing. nom. fem.) derives.
-Ancient Greek «ἔρως» ĕrōs (sing. nom. masc.)--> sexual love, desire, gives «ἔρωτα» 'ĕrōtă in the accusative, from which the Modern Greek «έρωτας» ['erotas] (sing. nom. masc.) derives.
-Ancient Greek «ἐλπίς» ĕl'pis (sing. nom. fem.)--> hope, gives «ἐλπίδα» ĕl'pidă in the accusative, from which the Modern Greek «ελπίδα» [el'piða] (sing. nom. fem.) derives
