Is it spelled casual or causal?<|im_end|>
<|im_start|>assistant
Both "casual" and "causal" are English adjectives. The word "casual" means relaxed or informal, as in "The partygoers came in casual attire." On the other hand, the word "causal" means involving or constituting a cause. This word is often found in the subject of statistics, as in "We could not prove a causal relationship from strong correlation alone."<|im_end|>

Can you give me some examples of contronyms?<|im_end|>
<|im_start|>assistant
Sure! Contronyms (also known as autoantonyms or Janus words) are words that have two opposite meanings. Some examples are: sanction (to approve or to punish), cleave (to stick together or to split apart), dust (to remove particles or to add particles), and oversight (to supervise or to miss).<|im_end|>
