utter, utterly, completely, totally 
[adjective/adverb]
[fa-lie-kant]
"Faliekant" originates from (the no longer in use) "faliecant": a non-right angle.
In daily speech, "faliekant" is mostly used as an adverb to amplify an adjective that expresses dissatisfaction. You will usually see the combinations "faliekant tegen" (completely against) and "faliekant mis" (totally wrong).
Examples:
– "O jee, het is faliekant mis met het openbaar vervoer vandaag, overal vertragingen."
("Oh dear, complete mayhem in public transportation today, delays everywhere." Lit.: "…it's gone utterly wrong…")
– "Roze behang in de slaapkamer? Daar ben ik faliekant tegen!"
("Pink wallpaper in the bedroom? I'm totally against that!")
Related words:
– Helemaal: completely [adverb].
– Volledig: complete(ly) [adjective/adverb].
Example:
– "Gast, ik ben volledig naar de klote…" – "Flinke kater zeker?"
("Dude, I'm completely wasted…" – "Big hangover, right?")
“”Faliekant” originates from (the no longer in use) “faliecant”: a non-square angle.”
I think we’d call that a right-angle (90 degrees)?
@ Chris
I’m looking for the word that is the opposite of a right (90 degree) angle…. a crooked angle?
Oei! Well Marc, thinking back to school geometry – gulp – I think there are the following:
Acute Angle – an angle that is less than 90°
Right Angle – an angle that is 90° exactly
Obtuse Angle – an angle that is greater than 90° but less than 180°
Straight Angle – an angle that is 180° exactly
Reflex Angle – an angle that is greater than 180°
(with a little reminder from the Internet 🙂 )
@ Chris
In Dutch we say “schuine hoek” (crooked angle) I’ll use ‘a non-right angle’ here … 🙂 thnx!
