IPA: /ˌæntɪˈklaɪnəl/
KK: /æntɪˈklaɪnəl/
Relating to a type of geological formation where layers of rock bend upwards, creating a peak, or to the plane of cell division in plants that is perpendicular to the surface.
The anticlinal structure of the mountain range was evident in the way the rocks were layered.
Anticlinal → It is formed from "anti-" (meaning against) and "clina" (from Latin "clinare", meaning to incline). The word describes a geological formation where layers of rock are inclined away from a central axis, hence 'against the incline'.
Think of 'against' ('anti-') the 'incline' ('clina') to remember that 'anticlinal' refers to rock layers that slope away from a central point.
