〜の限りだ

Expresses the speaker's own emotion at its highest degree. With nouns it attaches to emotion words such as 光栄・感激・痛恨, and with い-adjectives (羨ましい・嬉しい・心細い) it appears directly as 〜限りだ. It is formal and somewhat set, common in greetings and speeches; it describes only the speaker's feeling, so it cannot be used of a third person's emotions.

• 一人で暮らすのは心細い限りだ。

  ひとりでくらすのはこころぼそいかぎりだ。

  Living alone leaves me feeling utterly helpless.

• このような賞をいただき、光栄の限りです。

  このようなしょうをいただき、こうえいのかぎりです。

  To receive an award like this is the greatest of honors.

• 長年の努力が実を結び、感激の限りです。

  ながねんのどりょくがみをむすび、かんげきのかぎりです。

  My years of effort have finally borne fruit; I am deeply moved.
