In-Adverbials with Simple Past Tense

In-adverbials combined with the simple past tense typically express the 'size' or duration of a [+durative] [+telic] eventuality. As a result:

• With states, they are usually anomalous because states are [–telic].
• With activities, they are usually anomalous because activities are [–telic].
• With accomplishments, which are [+durative] [+telic], they are perfectly natural and express the duration of the event.
• With achievements, which are [–durative], they typically express the time elapsed before the event (onset reading). However, this reading is often more natural with the preposition within.
• With semelfactives, they are usually anomalous because semelfactives are [–durative] [–telic].

Syphilis

Caused by: The spirochete bacterium Treponema pallidum.

Signs and Symptoms

• Primary Stage

  Classically presents with a single chancre (firm, painless, non-itchy skin ulceration) that forms approximately 21 days after exposure. These ulcers are usually on the penis, in the vagina, around the anus, and in the mouth. The chancre disappears within 4 to 8 weeks without medication.

• Secondary Stage

  Diffuse rash which frequently involves the palms of the hands and soles of the feet. May include latent syphilis with few to no symptoms.

• Tertiary Stage

  Begins after primary and secondary symptoms resolve. Involves neurological or cardiac symptoms. Can lead to difficulties coordinating muscle movements, paralysis, gradual blindness, and death.

Question of Identity

“What do you mean by that?” said the Caterpillar sternly. “Explain yourself!”

“I can't explain myself, I'm afraid, sir,” said Alice, “because I'm not myself, you see.”
