Don't get this word confused with "horse," the animal! "Hoarse" means raspy or rough-sounding, especially when describing someone's voice. You've probably had a hoarse voice after getting a sore throat. "Smooth" means even or free of bumps; "artistic" means talented at art or creative activities, and "mountainous" refers to areas of land and means containing mountains.

"Frigid" means very chilly or cold. Therefore, the best synonym for "frigid" is "cold." While "snow" is cold, it is a noun, and does not mean the same thing as "frigid." "Different," "straight," and "solid" are each unrelated to the word "frigid." Therefore, "cold" is the best answer.

Have you ever been in a friend's house that seems almost too clean? Or walked by a lawn that was perfectly manicured? In situations like these, you could use the adjective "pristine," which means perfectly clean or untouched. The best choice for a synonym is clearly "spotless," which could also describe an impeccably clean environment. Both "dirty" and "marred" are antonyms, and "self-assured" simply describes a confident or assertive person.

The word "vivid" means very bright or lively. "Bright" is the best choice because it is a part of the definition of "vivid." Considering the other choices, "new" is unrelated in meaning to "vivid," "sight" is a noun that means the ability to see, and "cloudy" means foggy or unclear.

To provide further help, “sturdy" means not easily broken or tipped over, “comforting” means providing comfort and making you feel better, "agile" means quick-moving and athletic, and "risky" means involving risk-taking and therefore dangerous and uncertain.

Something that is “hideous” is ugly, gross, and unpleasant.

Delicate means fragile or easily damaged or broken, so "fragile" is the correct answer.

"Murky" means dim, not bright, hard to see through. A pond that you cannot see to the bottom of might be described as "murky" or "dim." "Dim" is the opposite of "bright."
