fledged

The word 'fledged' has its origins in the Old English term flycge, which directly described the state of a young bird whose feathers had grown sufficiently for flight. This root is related to the Old High German flucki and the Old Norse fleygr, all pointing to a common Germanic concept of being ready to fly. The addition of the common adjectival suffix '-ed' solidifies its function as a descriptor of a state or condition. Over time, the meaning expanded metaphorically beyond ornithology to describe any person or project that has developed the necessary skills or resources and is now ready for independent operation, maintaining the core idea of a transition to a state of readiness and maturity.

Structure: fledge (to grow feathers) + ed (adjective suffix) 'fledge' originates from Old English flycge, meaning "having the feathers developed, fit to fly." The '-ed' suffix is from Old English '-ed', '-od', '-ad', used to form adjectives from nouns or verbs, indicating a state or condition.
