horrid

Compared meaning: very bad or unpleasant (adjective).

比较义项：很糟糕的、令人不愉快的（形容词）。

• awful

  The most common and neutral choice; used broadly in everyday speech for almost anything unpleasant, with no strong regional or informal flavor.

  三者中最中性、最常用的词；日常口语中广泛用于形容几乎任何令人不快的事物，没有明显的地域或非正式色彩。

  The service at that restaurant was awful, so we decided never to go back.

  那家餐厅的服务很糟糕，所以我们决定再也不去了。

• lousy

  Informal, chiefly American; often implies poor quality or bad luck, and pairs naturally with words like mood, day or job, sounding too casual for formal writing.

  非正式用词，主要用于美式英语；常暗指质量差或运气不好，习惯与心情、一天、工作等词搭配，语气过于随意，不适合正式书面语。

  I've been in a lousy mood all week because work has been so stressful.

  这一周我心情一直很糟糕，因为工作压力太大了。

• horrid 本词

  Sounds slightly old-fashioned or childish, more common in British English; expresses a strong personal reaction of disgust or dislike, often in an exaggerated way.

  听起来略显老式或孩子气，在英式英语中更常见；表达一种强烈的个人反感或厌恶情绪，语气往往带有夸张成分。

  What a horrid smell! Someone must have left the fish out on the counter.

  好可怕的气味！肯定是有人把鱼放在台面上忘了收。

Awful, lousy and horrid all mean very bad, but the tone differs. Awful is the common, neutral word. Lousy is informal, mainly American, often about a mood or job. Horrid sounds old-fashioned and British, showing strong dislike. Not compared: lousy's old sense, 'covered in lice'.

这三个词在此义项上都表示很糟糕的、令人不愉快的，可互相替换但语气不同：awful最中性常用，lousy偏口语化、带美式随性语气，horrid略显老式或孩子气、语气更强烈更具个人反感色彩。这里不比较lousy「长满虱子的」这一本义。
