dangerous because of hidden risks
Very dangerous because something looks safe but is not, or because it can suddenly become unsafe.
Vzorec užití:
[treacherous] [conditions/road/ground/weather]
Častá chyba:
Learners sometimes use "treacherous" for any strong danger, when it usually suggests danger that is hidden, surprising, or greater than it appears. For clear, obvious danger, "very dangerous" or "extremely risky" is often more natural. Also, do not confuse "treacherous" with "tricky"; "tricky" can mean just difficult, but "treacherous" implies real risk of harm.
Synonyma
dangerous (More general and common; does not always suggest hidden or surprising danger.)
|
perilous (More formal and dramatic; emphasizes great risk, without necessarily implying hiddenness.)
|
hazardous (Often used in formal or technical contexts (e.g. work, chemicals), slightly less emotional than "treacherous.")
Antonyma
safe (Describes conditions that do not cause harm or risk.)
|
secure (Emphasizes protection from danger or risk, the opposite of being unstable or risky.)

disloyal and ready to betray
Not loyal and likely to turn against someone who trusts you, often in a very serious or bad way.
Vzorec užití:
[someone] is treacherous to [someone]
Častá chyba:
Learners sometimes confuse "treacherous" with "tricky" or "sneaky." While those can describe small, everyday behavior, "treacherous" usually describes very serious disloyalty or betrayal. It is too strong for mild problems in a friendship or a game. Also, do not use "treacherous" to describe someone simply difficult or annoying; it specifically involves breaking trust.
Synonyma
traitorous (Often used in political or national contexts; very close in strength to "treacherous.")
|
disloyal (More general and slightly softer; may not sound as strong or shocking as "treacherous.")
|
faithless (More literary or old-fashioned; can refer to breaking promises or romantic loyalty.)
Antonyma
loyal (Describes someone who stays with and supports others, even when it is difficult.)
|
faithful (Highlights steady support and keeping promises; often used in personal or romantic contexts.)

unreliable and likely to mislead
Not reliable and may suddenly fail or give the wrong idea when you trust it, like a memory or a feeling.
Vzorec užití:
[treacherous] [memory/feeling/appearance]
Častá chyba:
Learners may use "treacherous" only for people, but this sense often describes abstract things like memory, calm, or appearances that mislead you. In many everyday situations, "unreliable" or "deceptive" is more common; "treacherous" sounds stronger and more dramatic.
Synonyma
unreliable (More general; does not always include the idea of harming or betraying someone.)
|
deceptive (Focuses on giving a wrong idea; may not always suggest emotional harm or betrayal.)
Antonyma
trustworthy (Can be relied on without fear of being misled or harmed.)
|
dependable (Emphasizes steady and predictable reliability when you rely on something.)
