Why can you use either "την" or "τη"? Thought it was one or the other.
I think "τη" is more colloquial, and "την" is rather formal
And I thought τη would only be used before Κ, Ζ and Γ
Rules for retaining the final -ν: before vowels, before π, κ, τ, μπ, ντ, γκ, τσ, τζ, ψ, ξ, and for masculine pronouns always in the accusative to distinguish them from the neuter forms.
