Standard

semi-, correspond to, proportionate to, conform, imitate

Mnemonic

During a violent storm, a lone bird refuses to break formation, flying in a precise cross pattern across the dark sky. This is the standard route—every bird must hold the standard even when winds howl and lightning cracks. Deviation means death; discipline means survival.
Additional thoughts
Picture the bird's cross-shaped silhouette cutting through storm clouds—a living benchmark. The cross pattern is the measurable norm all birds train for. Storm = harsh test, Cross = rigid form, Bird = the one being measured against the standard.
Quick recall
A bird flies a perfect cross through a raging storm—that's the standard.
