Is 'Deus est meus vires' Latin for 'God is my strength'?
No, 'Deus est meus vires' doesn't mean 'God is my strength'. Instead, Deus est vis mea is the Latin equivalent. In the first, incorrect example, the noun 'vires' is in the feminine plural and the possessive adjective 'meus' is in the masculine singular. Latin nouns and their adjectives must agree in both gender [feminine/masculine/neuter] and number [singular/plural]. In the word by word translation, the noun 'Deus' means 'God'. The verb 'est' means '[he/she/it] is'. The noun 'vis' means 'strength'. The possessive adjective 'mea' means 'my'.
