Meaning of “Two-Faced”
To be two-faced means to be deceitful, hypocritical, or insincere — showing one attitude in public while secretly holding another.
It’s often used to describe someone who pretends to be kind or supportive but acts dishonestly or cruelly when you’re not looking.
In short:
👉 “Two-faced” means pretending to be someone’s friend while secretly betraying or criticizing them.
Other shades of meaning include:
-
Being dishonest or duplicitous in relationships or business.
-
Changing behavior or opinions depending on who’s around.
-

Origin of “Two-Faced”
The idiom “two-faced” traces back to ancient Roman mythology, particularly to the god Janus — the deity of beginnings, transitions, and doorways. Janus was depicted with two faces: one looking forward, one looking backward.
While Janus himself wasn’t deceitful, his image inspired later uses of “two-faced” to describe people who show two different sides.
By the 16th century, English speakers were using “two-faced” in a negative sense — referring to someone hypocritical or untrustworthy. The Oxford English Dictionary cites early examples where it meant “deceitful” or “duplicitous.”
So, from mythology to modern gossip, “two-faced” has always symbolized double-dealing behavior.
