用法筆記
This is the broadest sense of the word, covering both literal situations (vehicles, machines) and emotional or behavioural reactions. It works both attributively ("an uncontrolled sob") and predicatively ("the horse became uncontrolled"). Distinguish from sense 2: this sense focuses on the immediate loss of control, whereas sense 2 focuses on the absence of intervention over time.

用法筆記
Frequently appears in the pattern 'go + uncontrolled' or 'remain + uncontrolled,' emphasising that nobody is stopping the situation. Unlike sense 1, which describes an immediate state of lost control, this sense describes a longer-term trend that is allowed to continue. Common subjects include diseases (e.g., cholera, diabetes), economic problems (inflation, debt), and environmental issues (deforestation, pollution).

文法句型
uncontrolled + trial/study/experiment
uncontrolled + research/observation
用法筆記
Almost exclusively attributive (placed before the noun: 'an uncontrolled trial,' 'an uncontrolled study'). Not used predicatively — you would not say 'the trial was uncontrolled' in formal scientific writing; instead say 'the trial lacked a control group.' The term carries a critical nuance: it points to a methodological weakness, not a neutral description.
4. not limited, managed, or restricted by laws, rules, policies, or any formal regu

- unrestricted

- unregulated
specifically about the absence of official rules or oversight; common in economics and policy
- laissez-faire
borrowed from French; describes a policy of letting things happen without interference
- regulated
describes activities that are controlled by laws or official rules
- restricted
suggests limits or conditions placed on an activity
文法句型
uncontrolled + noun (development, access, power, use)
remain/seem + uncontrolled
用法筆記
Common in formal writing about law, urban planning, economics, and governance. The focus is on the absence of a regulatory framework — not that something is chaotic (sense 1) but that no rules exist to limit it. Distinguish from sense 2: sense 2 describes a problem growing worse despite awareness, while sense 4 describes an activity that faces no legal restrictions at all.
