What the source reads — Εὐοδία (Euodia) — a woman's name, feminine; Paul urges her and Syntyche to agree, and the next verse (4:3) calls them 'women who laboured with me'
What this version reads — 'Euodias' — the KJV gives her a masculine -as ending, the same move that turned Junia into 'Junias'; every other version keeps 'Euodia'
Paul names two women at Philippi, Euodia and Syntyche, and asks them to be reconciled; verse 3 calls them 'those women who laboured with me in the gospel'. The Greek Euodia is plainly feminine. The KJV alone prints 'Euodias' — a masculine form — the same masculinizing slip made with Junia. The context still calls them women, so the damage is lighter, but a named woman is left under a man's spelling. The Vulgate, the WEB and all three Italians keep 'Euodia'.
