Usage

V-てやまない

Explanation
てやまない attaches to a verb in the て-form to express a strong, sustained feeling or a persistent action. It conveys that someone does something wholeheartedly, without end, or holds a feeling very deeply. It is often used to describe positive, earnest attitudes (such as love, gratitude, generosity) or a relentless effort toward a goal. It can also emphasize a speaker’s conviction or sincerity toward others. Commonly used in literary or formal speech, and in written narratives; in everyday conversation you might hear more neutral phrases, but てやまない carries a stronger emotional charge. Examples: - 彼は人を助けてやまない。 → He never ceases to help people / He is always ready to help others. - 私は彼に感謝してやまない。 → I am deeply grateful to him. - 彼女は子供の幸福を願ってやまない。 → She longs for her child’s happiness with all her heart. - あなたの成功を信じてやまない。 → I wholeheartedly believe in your success. - 彼は自分の信念を貫いてやまない。 → He will not waver from his beliefs.
彼は困っている人を放っておけず、いつも手を差し伸べてやまない。
かれはこまっているひとをほうっておけず、いつもてをさしのべてやまない。

He can’t stand by when someone is in trouble and is always lending a hand.

私は彼に対して感謝してやまない。
わたしはかれにたいしてかんしゃしてやまない。

かのじょはじぶんのゆめをあきらめず、さいごまでちょうせんしてやまない。
