Questions & Answers about Mir sind leider zweierlei Fläschchen heruntergefallen!
Why doesn't zweierlei have an adjective ending to match the plural Fläschchen?
Adjectives ending in -erlei (meaning kinds of or types of) are invariant. This means they never change their endings to match the noun's gender, case, or number. It is always zweierlei, regardless of the noun that follows it.
Why use Mir sind ... heruntergefallen instead of translating I dropped directly?
While you could say Ich habe ... fallengelassen, German usually prefers the dative construction Mir ist/sind ... heruntergefallen for an accidental drop. It literally means the bottles fell down to me, which emphasizes that it was an unintentional mishap rather than a deliberate action.
How do we know Fläschchen is plural here if it lacks a plural ending?
Nouns ending in the diminutive suffix -chen are always neuter and never change their form in the plural. You can tell it is plural here because the helping verb is sind rather than ist, and because zweierlei inherently implies multiple bottles.
Why does this sentence use sind as the helping verb instead of haben?
