inda

The thing you are worthy of takes je or de: inda je laŭdo. But the standalone adjective is the smaller half of the story. Its real work is as the suffix -ind-, which bolts onto any verb and means "worth doing": legi gives leginda, worth reading, vidi gives vidinda, admiri gives admirinda. Once that clicks you stop needing whole English phrases. Malinda is unworthy, indeco dignity, and indas used impersonally means "it is worth it" - indas provi.
