Here's what Yiddish writer Isaac Bashevis Singer had to say about the language in his 1978 Nobel Prize acceptance speech:
"Yiddish language - a language of exile, without a land, without
frontiers, not supported by any government, a language which possesses no words for weapons, ammunition, military exercises, war tactics ...There is a quiet humour in Yiddish and a gratitude for every day of life, every crumb of success, each encounter of love. The Yiddish mentality is not haughty. It does not take victory for granted. It does not demand and command but it muddles through, sneaks by, smuggles itself amidst the powers of destruction, knowing somewhere that God's plan for Creation is still at the very beginning ...
In a figurative way, Yiddish is the wise and humble language of us all, the idiom of frightened and hopeful Humanity."
