Example Sentences Using Adjectives That Start With A

A word list helps, but seeing the word do its job helps more. Here are 18 A-adjectives in real, mostly work-shaped sentences. When you want to reach for stronger, more vivid word choices, the same approach applies: pick the precise word, then test it in the sentence.

Tips for Using Adjectives That Start With A

Once you've found the right word, a few habits help it land.

• Use fewer, better words. One precise adjective beats three vague ones. "An astute analyst" says more than "a really smart, clever, sharp analyst."
• Match the register to the room. "Adorable" fits a thank-you note. "Accredited" fits a vendor evaluation. Reaching for the wrong tone is more distracting than a plain word.
• Mind the order when you stack them. English has a usual sequence for multiple adjectives (opinion, size, physical quality, shape, age, color, origin, material, type, purpose), which is why "a charming old amber bottle" sounds right and "an amber old charming bottle" doesn't. If you want the rule in full, Cambridge Dictionary lays out the order adjectives usually follow.
• Check how the word lands. "Ambitious" can read as praise or as a quiet warning, depending on context. Make sure the connotation matches what you intend.
• Let a strong verb do the work. "Sales jumped" says more than "sales saw an aggressive increase."
