Erster
Erster is a German adjective form meaning “first” when used before masculine singular nouns. It is the nominative singular form that typically appears without a definite article or after an indefinite article, as in ein erster Tag or ein erster Schritt. After the definite article der, the corresponding form is erste: der erste Tag. The word changes its ending to agree with gender, case, and number, so it has different inflected forms such as ersten (masculine accusative), erste (feminine nominative/accusative), erstes (neuter nominative/accusative), and die ersten Tage (plural).
Common usages include phrases like ein erster Versuch (a first attempt), der erste Tag (the first day),
