Root Explanation

Syncline → It is formed from "syn-" (meaning together) and "cline" (from the Greek "klinein", meaning to lean or slope). The word describes a geological formation where layers of rock are folded downward, creating a trough-like structure that leans together.

Memory Tip

Think of layers of rock 'leaning together' ('syn-' means together and 'cline' means to lean) to remember that a syncline is a downward fold in geological formations.
