How to say "horrid" in Japanese

• 忌まわしいいまわしいCommon
  i-adjectiveCovers horrid at its strongest: abhorrent, abominable, detestable. Use it for things that inspire real disgust or loathing — an abhorrent deed, a detestable episode one shudders to recall.
  考かんがえるだけでも忌いまわしい。↗

  The very thought is abhorrent to me.
• 最悪さいあくCommon
  na-adjective, interjectionThis colloquial word covers horrid in the everyday 'awful, terrible' sense — a horrid day, a horrid experience. It is the natural spoken choice when horrid simply means something awful.
• ずいぶんJLPT N4approx.Common
  na-adjectiveUse it for horrid as contemptible or reprehensible — a horrid thing to do or say. Otherwise a marginal match: the word really means 'terrible' or 'contemptible', and is usually written in kana alone.

Use 「忌まわしい」 for horrid in the strong sense of abhorrent or detestable, 最悪 for the colloquial 'awful, terrible' sense, and 「ずいぶん」 when horrid means contemptible or reprehensible, especially of behavior.
