What does hypothesized mean?
Hypothesized is the past tense and past participle of hypothesize, meaning to put forward a tentative explanation for something. It is especially common in scientific, academic, and formal writing: a researcher hypothesizes a relationship between two variables and then designs observations or experiments to test it. The word differs from words such as proved because it describes a proposition that is plausible and open to investigation, not an established conclusion. It can also function as an adjective, as in a hypothesized cause, where it characterizes an explanation that is being considered but remains unconfirmed. The related noun hypothesis has the irregular plural hypotheses. Although hypothesized and hypothesised are both standard, the spelling with z is typical in American English, while the spelling with s is common in British English. In careful scientific prose, the word should be paired with evidence or a method of testing rather than presented as fact.

Where does hypothesized come from?
The word comes from Greek hypothesis, meaning a supposition or proposition placed under examination. Its underlying elements are hypo, “under,” and thesis, “placing” or “setting down,” expressing the idea of placing an account or proposition under scrutiny. The Latinized form hypothesis entered English in the early 17th century. The verb developed from this noun, and the modern spelling with -ize is standard in American English, while -ise is common in British English.
